Lightweight Backpacks / Integrated Platform / Divide

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.  

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.

    Great frame - careful if you have bony hips

    Posted by Justin Sermeno on 9th Apr 2019


    There are some amazing things about this pack. With a little adjustment, you can perfectly distribute the weight of the pack between the shoulder harness and the hip belt to your liking. The frame is completely rigid vertically yet it rotates to your movements and feels more like an internal frame pack than an external frame pack.


    I'm 5' 7", 140 lbs. I'm a climber and I have bony hips. Out of the 20 or so packs I've owned throughout my lifetime the hip belt is the most uncomfortable hip belt I've ever used. The foam is stiff and a large portion of the weight is focused directly on the hip bones. After a weekend out with 50 lbs my hips were bruised, red, and swollen. The bedrock and paradox blog has written about similar experiences with the hip belt.

    I'm okay with all of this. I don't have the body type of a typical hunter and I bought the pack with the intention of modifying it to create the perfect load hauling climbing pack. I don't know of any other frame that can create such a lightweight hauler. For anyone else in a similar situation, my plan is to build a new hip belt with softer 2lb density foam in the sides.

    Divide 4500 Ultralight Backpack grey

    Posted by Farwalker on 31st Jul 2018

    I used this pack for FIVE months straight this year (March - July 2018) for 2,000 miles of the Pacific Crest Trail. Absolutely BOMBER! Carried my heavy winter/spring loads perfectly, then all the water I needed for the desert sections and swallowed the bear canister for the Sierra like no other pack I own. I've tried all those "ultralight" packs and NONE of them compared to this in carrying comfort and capacity. It was easy to change belts when I lost weight, no problems. Washed twice in a tub by hand and the dang thing still looks almost new! No failures on hardware and no problems adjusting for size or loads. It's even comfortable with a loose waist belt which I did for climbs since I like to belly breathe deeply when going up the passes. If you want a pack that will carry your loads in comfort, last for thousands of miles under the harshest conditions, this is the one!

    Awesome pack

    Posted by Jim on 11th Jun 2018

    Love, love, love this pack – most comfortable I've ever worn. A bit heavy for a lightweight pack, but makes every pound I put in it seem like three quarters of a pound. really versatile, too – I've carried 15-65 pounds in it. Only pack I need :-)
