Not for Expeditions
I used this pack for a 3 week backpacking trip in on the superior hiking trail and it worked great when only loaded with 40lbs or less. I then took it on several more weekend and weeklong trips and it seemed fine aslong as you don't fill it full. However, this winter i did a 5 day trek over the presidential mountains in NH and it was not up to the task, it flounders under the expedition weight of 50lbs and the mesh hip and shoulder straps easily absorb water and then freeze stiff as a board. It also started to show sines of stitching fatigue on both the compression straps and the hip-belt attachment to the pack. All in all a great starter pack for around $150 but i now have an osprey aether 85 and am hoping that that is the last bag i ever have to buy.
