Ultra fabric features a woven Ultra High Molecular Weight Polyethylene (UHMWPE) face fabric laminated to a waterproof backing. Ultra fabric boasts extremely high abrasion and tear resistance and is the strongest fabric we offer.

Curved Carbon Fiber Air Stays combined with a Lycra back panel create a gap between your back and the pack. The air gap helps keep your back cool while also preventing items from rubbing against you while hiking.

Roll-top closure (like our dry bags) keeps water out, and lets you roll down the top as your gear load shrinks. All seams and attachment points are taped, making the pack highly water resistant. We still suggest using dry bags for your important items like your sleeping bag.

Comfy 3/8" thick by 2.5" wide padded contoured shoulder straps designed for smaller torsos and a padded belt. Both the straps and the belt have a daisy chain for clipping on items, and an adjustable position sternum strap is also included. The belt and shoulder straps have 3D mesh on the underside. This gives them a little bit more cushion, and the belt also has more texture for better grip.

Side pockets are sized to fit 1 or 1.5 liter bottles, or 2L soft bladders. They are positioned low on the pack and slanted forward for easy access without removing the pack. The pockets have drainage holes at the bottom, and elastic that keeps them tight at the top.

Large stretchy mesh center pocket is great for quick access items. Mesh also lets you dry wet clothing and gives you a clear view of your gear.

Side compression straps are made from non-stretchy Dyneema® cord for squishing down the pack volume. They also allow you to stand tall items like trekking poles or an umbrella in the side pockets.

A top strap, and base straps allow you to lash on extra items to the top or base of the pack. The straps come off if you don't need them.

The 60L pack size has enough space for 5-6 days of food and ultralight gear. The pack can be compressed down with the roll top and side compression straps for short trips or use the top strap and base straps to lash extra stuff to the outside for long carries.

All standard Bear Canisters, including the Bearikade Expedition and the BearVault 500 will fit in the upper half of this pack standing on end. Wrap your canister with your sit pad, or clothing to help prevent abrasion to the inside of the pack material. 

Fits into an airplane overhead bin with the top rolled down to the frame.
