Hunting Backpacks / Integrated Platform / Brooks:

From daypack to load monster, the Brooks quickly converts from 1200 ci daypack to 2400 ci batwing to 5800 ci weekender to 7400 ci hunting backpack.  The Brooks offers a weather resistant rolltop with quick access fully separating zipper, plus two large zippered side pockets offering storage and organization.

Handmade in Grand Junction, Colorado, USA.

Seek Outside Backpacks all feature:

  • X-Pac™ Backpack Fabric - forever waterproof & durable.  No more raincovers!
  • Adjustable Frame Height - 24" -26" - 28" - Frame Extensions allow you to dial your pack height to your torso length or expected load weight.  Hunt small, haul tall.

Rain Cover / Seam Sealing:

  • Main pack bag is made of X-Pac™ waterproof material and features a waterproof rolltop closure.  Seam sealing the outside seams is recommended for exceptionally wet environments.  
  • Water can penetrate the side zipper, but usually not in a rain situation with the pack upright - the zipper flap does an excellent job of repelling rain.  
  • Waterproof stuff sacks are recommended for exceptionally rainy conditions, and drybags for submersion or severely wet conditions such as bushwacking or canyoneering.  
  • Side pockets are 500D Cordura and are not waterproof.

    Wow! Highly Recommended!

    Posted by Robert on 4th Oct 2017

    I tested this pack against a Kifaru and Exo Mountain and it was by far the most comfortable. I've tested it with up to 104 lbs and it performed phenomenally. My reservation with buying this pack was that I already had several large volume packs (Mountainsmith, Kelty, Jansport). However, the way this SO carries heavy weight is not even comparable to the traditional backpacking brands. The only reason I give 4 stars instead of 5 is the challenging experience with customer service. They had a recall on this pack b/c of incorrect buckles. They did not return my emails, then when I called them they told me they weren't sure how long it would take to fix the recall issue and send my pack back to me. Long story short, I had to call Argali Outdoors (where I bought the pack) and get them to address my issue with the SO folks. That said, I believe they are great folks. I just had a not so great experience. In the end they eventually fixed the recall issue in a prompt and professional manner.

    Seek Outside Note: We investigated where the disconnect was which was that we called the customer instead of answering the ticket. In the future, when we directly call a customer to resolve, we will note it in the ticket before closing ticket. Thanks

    Preliminary review - owned it for 1 day...

    Posted by Daniel Brassard on 1st Sep 2017

    I've been stomping around my neighborhood with 65 pounds in my old dead bird naos 70 liter pack. When the brooks arrived, I put the entire pack in the brooks... *and still had to cinch it down*.

    First loaded impression, the Brooks is more comfortable than my old naos or my old-old bora.

    The suspension layout was intuitive enough that I adjusted it easily enough. The conversion to a 1200 ci daypack eluded me until just now... the compression straps wrap around the *frame* and clip to themselves. I couldn't find the loops. No loops needed!

    The postie who dropped the pack off (she's a mountain fanatic and a buddy of mine, now) and I were very pleased by the build quality. Very solid, and the functional design touches make me jealous I didn't think of them.

    The two strap waistbelt seems like a particularly neat idea so far. Dad-bod lard aside (darn kids!), I like it. I put my belt buckle between the two straps, and that seemed to cure the pouching pant-front I've always sported when backpacking. We'll have to see when it's game time, of course.

    With a bit of luck, I'll be putting moose quarters (or eighths... maybe sixteenths. I'm a shadow of the man I was) in the pack the last week of september, so I'll update my review.
