????Bottom Access:There is a divider between the sleeping bag compartment (at the bottom) and the main compartment at the top.You can access the main compartment from the bottom if needed.
????SPECIAL:the 80L packs have the zippered opening on the side to get to the inside middle of the bag. So, you can access the middle of the bag from outside without having to lift the top and empty everything to get to the middle.
????Hip-belt adjustable length:80-145cm/31.5-57.1in. It's not typically worn at the waist, but somewhat lower, on the hips. It's often beneficial to comfort and balance to adjust belt position while hiking, so plan to occasionally use less than the full 57" as you reposition.
????Hydration Compartment:Separate bladder sleeve in the main compartment.Big enough or a 3 liters hydration bladder.
????TORSO-LENGTH ADJUSTMENT- 8 stage height adjuster at the back, held in place with a thick hardened area with magic tape.
