Pentagon Deos Rucksack 65L

The Pentagon Deos 65 is a full expedition bergen rather than a large daysack. The body is 100% nylon 500D Cordura® running YKK® zips and Duraflex® buckles throughout, top-loading into a single 65 litre main compartment with a drawcord throat and a lid that cinches down over it. Two detachable side pouches add 5.25 litres each, so the pack runs at 65 litres stripped or a little over 75 with both mounted, and drops back to a narrower profile when you take them off.

The carry system is the part that matters on a load this size. Pentagon's TBA adjustable back system lets you set the back length to your own torso instead of accepting a fixed size, and the padded waist belt is deep enough to actually transfer weight onto the hips rather than just steadying it. The belt detaches entirely, and carries its own MOLLE/PALS webbing for pouches within reach. Dual-level compression cords pull the load in as it empties, and MOLLE/PALS panels run across the lid, both sides and the waistband.

For weather, a full rain cover lives in its own pocket in the base and pulls over the packed bergen without unpacking anything. Hydration is built in, with an internal reservoir sleeve and a tube exit port at the side, and fastening straps at the lid and base take a roll mat or a sleeping bag on the outside.
