    Divide 4500 Ultralight Backpack 

    Designed for the ultralight backpacker and backcountry adventurer who needs both light weight and comfort under serious loads, the Divide bridges the gap between traditional ultralight backpacking and load hauling external frames.  

    Our patented Articulating Frame and Ultralight suspension rides close to the body and moves under light loads, yet is vertically rigid enough that load size is limited only by the users physical fitness. Other 2.5 pound packs do well with 20 - 25 pounds, and struggle above.  The Divide thrives with 30-50 pound loads and is capable over 100 pounds.

    With a proven feature set tailored for lightweight backpackers, pack rafters, and backcountry skiers, the Divide also delivers on ultralight backpack hunting trips where weight is of utmost importance.

    Handmade in Grand Junction, Colorado, USA.

    • Tapered main bag adapts to large loads, and rolls down to hug smaller loads.  When rolled down to the top of the frame the Divide is little more than 3000 cubic inches, but at full capacity balloons to 4500.
    • Dimensional side pockets with shock cord closure.  Uncinch, access a bottle or snacks, and recinch with one hand on the fly.  Shock cord is user replaceable for long service life.
    • Rear mesh pocket for storage of wet or quick access items.
    • Dual side compression with unbreakable aluminum bachelor buckles.
    • X Pac Backpack Fabric - no more raincovers.
    • Lower compression straps hold a bear can, sleeping pad, crampons, etc.





    • Pack bag height closed: 32" (with two rolls of the roll top)
    • Top circumference: 40.5"
    • Base circumference: 36"
    • Rear Pocket: 10" by 14" by 5"



    • Base weight 2 lbs 12 oz Alpine Gray, 2 lbs 15 oz Expedition Olive (w/ small belt)
    • Removable strapping adds 2.6 ounces (over the top, roll top cinch, dual lower straps) 
    • Horizon Cross Stay adds 2.5 ounces
    • Weight as packaged 3 lbs 1 oz in Alpine Grey, 3 lbs 4 oz Expedition Olive


    Rain Cover / Seam Sealing: 

    •  A rain cover is not needed for main pack bag since it features waterproof material and a watertight closure. Waterproof stuff sacks are recommended for exceptionally rainy conditions, and dry bags for submersion or severely wet conditions such as packrafting or canyoneering.  Sealing exterior seams with Aquaseal will enhance waterproofing.  Unsealed seams will leak in severe conditions.


    Bear Cans: 

    • All bear cans will fit horizontally in the upper 2/3 of the bag
    • Bear cans may be strapped on with lower compression straps 
    • Bear cans may be carried under the top strap



    • Suspension is 500D Cordura and 3D spacer mesh. Hypalon and 500D Cordura reinforcements
    • Pack bag is made from X21RC xpac (grey) or X42 xpac (olive).  X21 represents an excellent balance of durability and weight for on trail or lighter duty uses.  X42 easily stands up to all but the most abusive of applications.

    1. pull the trigger on the 4500 divide

      I have written a review on here before but feel I must do another one. I just returned from a week long hike where I really got to see how much better this pack is the others are here are just a few points. It rained like hell and my buddies packs where soaked and they carried around wet heavy packs for days mine was bone dry and everything thing in it was bone dry. One buddy had a rain cover but between the cover coming on and off and the wind issues while it was just a pain we called it his parachute he hated it but I got a great laugh about it. My pack was very comfortable and I carried some larger loads then I had to but with water food and gear I was still comfortable they were not. To be nice I took my turn with there packs and wow what a difference they loved mine I hated there packs. This pack is not cheep but I bet if I sold them 5 miles into your trip you would pay twice the amount and be happy.I looked for a month online and in stores and was hesitant on getting a pack online so for me it was a step of courage but the right move for sure. With all the thru hikers and lightweight gear being made from everything like tents sleeping pads sleeping bags pots ect ect I would LOVE to see a smaller volume pack made as well something around the 50 liter area as there are so many pack in that range but all are not comfortable when you add the water and food weight.
      The system these guys have is not only comfortable but easy to carry and I have owned 20 packs in my days. The day they sell I smaller lightweight pack I will order another pack and I will be set with the two packs and I know others will buy them too. As far as I am concerned the x pac material is the best for the outdoors period nothing else covers all the bases I have one Cubin fibre backpack but they are like a bic lighter you use them for a short period of time and they get tossed there are worn thru worn out I cant see ever getting something that lasts a season or long thru hike and its done. BUY THIS PACK YOU WILL NOT REGRET IT

    2. Best packrafting backpack out there

      I just love this backpack. My main use for it is packrafting. The Divide got everything you're looking for in a packrafting backpack; It's light, it's comfortable, it's as waterproof as any cuben backpack available, it can carry heavy, it's great looking, it sits perfect on the bow of the raft, it's durable, it can carry big volume, it's got a dedicated packraft/barrel "holder", it's adjustable for any torso length, load lifters that's actually useful, huge hip pockets that you can open with one hand, NO hydration port (which is a good thing for packrafters)... I could go on, but these are the important facts that makes this pack so much better than previous hyped "packrafting backpacks" like HMG Windrider (why is this even considered to be a packrafting pack?).

      Thank you Seek Outside for making the best packrafting pack available.

    3. Please read

      Im a hunter, bushwacker, plane traveller, trail maker, car camper, bike rider, snowboarder and more. Ive BOUGHT and OWNED gregory, ULA, Granite Gear, Military ILBE bags, foreign molle bags from the dutch army, kelty, and KUIU.
      This is the one. After 3+ years of trying everything to find my fit - short of ordering a Mchale (and I would have if this didnt work) im finally satisfied with my pack.
      Lightweight, well designed, WATERPROOF (at least for western washingtons standards) spacious yet collapseable.
      I am 6'1 220lbs and I can fit my backpacking gear into my bag with room to carry our older dachsund in the outside mesh pocket when she gets tired, 55lbs no issues long distance.
      I use my bag for smaller bikepacking trips and am able to accurately compress the bag . The mesh pocket works well to get mushrooms during the spring and fall. Carries wood well.

      ONE THING TO NOTE - top lids slide around and dont work well with this bag when not full. I cut and resewed my buckles to use the lid on the upper half of the back of the bag, but it doesnt come this way

    4. Tried and tested

      First of all i spent a ton of time looking for a backpack that has a balance of durability and is lightweight but still able to haul a load when needed.I looked at the curcuit and other pack from ula and tons of others but decided on the divide for the following reason.FIrst I had my seams sealed by seek outside and my pack has been in a lot of rain and my pack has been bone dry.Love the idea of not haveing a backpack cover that will be caught in the wind or having to look for it all the time.
      Pack is a great size super comfortable and very adjustable.I wanted a pack for longer hikes but wanted one that will last for years not a cuben pack I need to replace each year..
      I chose the x42 material and I would rate it heavey duty strength and maybe even overkill but for two ounces more I am okay with that.The fact it's water proof is HUGE for me nothing is wet and don't carry a wet heavey bag.I was very hesitant on ordering a backpack not seeing it but in every way it's better than I thought it's unreal.My friends all have seen it now and are so impressed.I am pretty picky and can count on one hand how many times things have been much better than I thought but this in one of those times.The staff have been excellent from start to finish.The cost is a little more than other but this is one of them things you get what you pay for and in this care more than I payed for. Pockets are awesome and bag locks down a load super well.The straps come super long so they can be trimmed almost everywhere to save more weight.I can't tell you the difference with this pack compared to other when you have 25 pounds or more and when you get 35 and more you can't even compare.I am in Canada so for me it's another 30 percent on top of the price and I still feel great about this pack as I know I will have it for years and years.I can't comment on the x21 but for me and adding 3 oz for the x42 I know this pack will take what I give it and keep me happy for years and years.I am convinced that if this was in the local REI it would be the best seller hands down.
      In conclusion I am sure I can get this pack under three pounds with trimming of straps and removing the over the top strap the horizon stay ect and I have a full framed durable pack able to carry small and larger load with comfort and be happy for years.My money does not come easy so I try to make smart purchases and go by the thought of buying the right thing once not the wrong thing two or three times and this was the right purchase.I don't think buying a pack a pound lighter that wears out in a year and is hard to carry with all gear and food makes sense ever.Best backpack purchase ever.

    5. Delighted with my Divide 4500

      I believe that the Divide 4500 may be the "do everything" pack that I've been looking for.

      I'm a "lightweight" backpacker and also a Scout Leader who takes lots of scouts on overnight trips. When I'm backpacking solo or with a small group of capable hikers, I rarely have over 25lbs in my pack including consumables and my ULA Catalyst or GG Mariposa work just fine. I like both of these packs and they work well with loads under 30 lbs. However, I'm also a Scout Leader who takes new scouts on trips and I invariably end up carrying extra gear - troop first aid kit, extra food, etc just in case. Recently, I hauled 45 lbs on an overnight scout trip to a dry camp using the ULA pack and was miserable as the suspension jus't cant carry that much weight comfortably.

      I am also taking 2 scout crews to Philmont and know that I will end up with over 40 lbs due to the way the trips are outfitted with crew gear and food. So, after reading all the reviews (particularly "Section Hiker") about the Divide 4500, I decided to take the plunge and add a pound or so to my pack weight in order to get the load carrying capability I need.

      I've taken the Divide 4500 on two overnight trips so far with about 30 lbs total weight so have not yet tested it at my upper weight limit. Here's what I can say about it at this point:
      1. The hip belt and harness are the most comfortable I've ever used. The hip belt is wider and a better "wrap" than my other packs and way more comfortable. I'll still have to see how it does at higher weights but I expect it to be great. Since the torso is fully adjustable, I've been able to "dial in" a perfect fit .
      2. The pack body has all the features I wanted (expandable front mesh pocket, roll top, large side pockets) plus the ability to compress and use as a day pack - Important to me for use in ascending "Baldy" at Philmont.
      3. The material and construction is best in class. The quality of workmanship is superb.

      The one area that I was concerned about was the ability of the side pocket to hold two 1L "Smart Water" bottles. After receiving the pack and loading it, the side pocket did not seem tall enough to secure two of the bottles on one side. However, after using the pack on two trips, I can say that the side pocket held the two bottles securely. The water bottles were accessible while hiking and held the bottles securely in place when bending over. That was a key concern that has now been alleviated. If you carry the tall 1L water bottles, you won't have any problem with securing them.

      Finally, I like the pack so much that I bought one for my "soon to be" Eagle Scout for the trip to Philmont.

    6. Solid pack

      I received my Divide 4500 on Wednesday, December 21st. Unfortunately, someone had forgotten to include the sternum strap. I called Seek Outside and after a chat with Luke, a sternum strap was being sent my way. They also kindly allowed me to exchange my medium hipbelt for a small. NOTE: I have a 32" waist (measured with a seamstress's tape), and the small hipbelt fits perfectly.

      The strap and belt arrived on Thursday, December 29. Just in time! I had a trip planned for an off-trail wander in the Ojito Wilderness with my longbow and a few buddies. We spent the night on a high bluff under the glow of the Milky Way. Coyotes serenaded us and the piƱon smoke was the smell of wildness.

      In the morning, we shouldered our packs and headed across the badlands on a compass guided ramble. My Divide 4500 carried like a dream! (Almost...see note below) I was able to shoot my 72lb draw-weight bow while wearing it. I carried about 35lbs in the pack and had no problems with discomfort other than when a cookpot was poking me in the spine. (My careless packing; soon remedied.)

      The flexibility of the suspension allowed me to leap across gulches and bend over to pick up arrows. It rested lovingly on my hips and was stable, supporting the load well. I had no problem with the rigid framing impeding freedom of movement nor did the frame base scrape my tailbone.

      I do have a bit of a feeling that the pack drifts backwards somewhat at the top. This is despite packing it properly, adjusting the sternum straps, etc. Perhaps I need to bend the frame slightly? Any feedback would be appreciated.

      As noted by Philip Werner, the shoulder harness is wide. I am not a tiny guy, (6'1", 185 lbs.) and it works for me, but just barely.

      Sometimes I like to backpack shirtless, and the mesh on the hipbelt and shoulder straps seems rather abrasive. Not a deal breaker, and perhaps it will soften up after use.

      It would be nice if at least one hipbelt pocket was included instead of only being available as a $25 add-on.

      All in all, a great experience, and if the pack ends up carrying the 50 lb load that I plan to carry in the snow at 12k feet in February, it will enter the pantheon of backpack divinity! I should add that due to the rather hefty price tag, It will have to last for at least a decade for it to enter that exalted state! We shall see.

      Keep in mind that all of the above is only an initial impression after one outing. I often find that it takes me up to a year of use with gear before I have concrete opinions based on sufficient experience.

      I do, however, have good vibes and high hopes for my Seek Outside Divide 4500!

    7. Update on the previous review "HAPPY WITH 650 MILES ON IT"

      Now at 2400 PCT miles on the green Divide with 2" extensions this year. Except for scratched paint on frame there is no obvious wear. With a magnifying glass you can see fuzzing of the fabric near the waist belt and on the bottom. And the top fabric has subtlety bleached in the sun. And the padding in the shoulders has flattened a little bit. I'd guess the pack has at least 80% of its life left (~10,000 miles) which realistically will probably take me to my grave.

      I have decided the bachelor buckles on the bottom are fine, but the ones on the sides are annoying, would rather have normal buckles there. They have a tendency to unhook when not tight, which seems to happen whenever I stop and take something out of the main compartment. And then I inevitably don't notice until I have my pack on. The one on the bottom don't seem to come accidentally off unless you completely empty the pack which isn't a problem.

      Only semi-complaint I have overall is that some of the reviews I read online made it seem like this pack was nearly waterproof and wouldn't benefit much from a pack cover. In my experience in Washington, aside from the fact that the material won't soak up/retain a ton of water this pack needs a liner and/or cover just as much as any other. The water just wicks straight through the seems. Really, more a problem with incorrect expectations on my part than a problem with the pack. To be clear, I have not seem sealed.

      I still give the pack 5 stars and consider the money well spent. I see no reason that I would shop for another pack unless I go crazy and go super ultra light. Thanks for making an awesome pack seek outside!

    8. 5 star pack

      roll top, water proof, durable, reachable side pockets. Amazing frame great load transfer, pack will touch your hips and lower back leaving your upper back with some air flow. Mesh is rough enough to take off some of your skin, I doubt it will rip. Very nice wide shoulder straps and comfortable hip padding. Good bag shape, smaller at the bottom and wider at the top makes for easier to put things in. Bag is huge, easily fit my 30 degree kit; excited to try it out this winter. on 24th Oct 2016

    9. Finally found a pack that fits

      After trying (and suffering through) numerous internal and external frame packs, I am in awe of how well this pack carries a load. I only have about 30 miles on it so far, so I can't comment on long term durability, but the materials and construction leave little doubt it will last a long time.

      The hip belt is amazingly comfortable, and the way it actually sits around my hips, I don't have to tighten the waist strap as much as other packs.

      The frame and hip belt distribute load very well. My max so far is ~45#, and likely won't carry much more than this. But it worked great from 45# down to 15# on day hikes.

      Wasn't sure about the bachelor buckles when I bought it, but I now love them. Much easier to access things that are lashed than traditional ones.

      The stash pocket and water bottle pockets work great and are are big enough to carry things I need to access during the day. Got caught in a downpour hiking in Glacier NP and the inside of the pack was bone dry. I haven't seam sealed it, though I may just for peace of mind.

      Prior to getting the Divide, the pack I had the best luck with was an older Gregory. But after 10 miles or so my hips and back would get sore, even with 35-40#. I cruised along with 45# in the Divide and the only thing that didn't keep up and feel great were my lungs.

      I honestly have nothing negative to say about the Divide 4500. A roll top bag isn't big on organization, but I knew that going in. It's lightweight, rugged, waterproof, adjustable, and carries a load like nothing I've encountered.

      Thanks for making such a great product!

    10. Works well for me

      Setup: Divide 4500 in Olive with multi-lid. Used 2" extensions to the frame for my longer torso length. Adjusted belt height so that the pack rides as high as possible. Added belt and shoulder strap pockets from another vendor.

      I've VERY pleased with the way this pack carries. I have over 70 mile on it so far, with pack weights from 19 #'s (short hike) to 35 #'s on several longer hikes. The weight all comes down on my hips; just as everyone said that it would. I like it! Admittedly this may be partially because I have paid more attention to learning about pack adjustment than I did with my old pack. The various videos available were helpful. When I tighten the load lifters they actually work.

      The material is very rugged. I could probably have gotten the lighter material and saved the weight. But this material is great.

      The mesh pocket is also very rugged and works for many of my items that I need easily accessible. The bottle pockets do the job as well. I like that they actually have a shape so that the bottle does not have to take up volume from the pack.

      The multi-lid was a later purchase. I felt I needed a bit more volume for some scout camping when I don't have as much control over all of the gear I carry. It works well. I like the internal zippered pocket for my valuables. I likely will not use the lid all of the time.

      I felt I wanted more pockets so I added some aftermarket ones on the belt and straps. Makes the pack more user-friendly for me.

      I agree with with another reviewer that the lower side compression straps could have been an inch higher but they work OK where they are.

      Again, I'm more than just a bit happy with this pack.
