How Long Have You Been Using This Product: Less than 1 month

I picked this pack up to replace a 30L frameless pack for day hiking and overnight trips. Ive used it with 20lbs loaded in it and it is night and day compared to my other pack. Way less sweat on my back and the weight is on my hips instead of my shoulders making the 20lbs feel MUCH lighter than it was. I picked this pack over the Talon 22 because of the AG suspension and how it has more air between the pack and your back. I packed all of my PCT overnight gear in for my section hikes of that trail and it fit just barely as im a minimalist. Highly recommend!
