Full disclosure … I just got this Elevate 22, but I am already impressed. I have a 19” torso length and originally ordered a size medium. I loaded it up with about 20lbs of kit and just could not find the sweet spot. I returned it for a size large and found both 20lbs and 12lbs loads to carry very comfortably on my body frame. The 12lbs load felt quite light indeed! I have never owned/used a “frameless, its just a bag” style pack but I am really looking forward to using this on extended day hikes into the back country looking for pristine “blue lines” on maps to fly fish. I plan on packing water bottle/filter, food, fire starter, headlamp, insulation layer, rain jacket, fly boxes, etc…enough for a day’s adventuring.
