Just finished six and a half months finishing the AT and this pack delivered from start to finish. I have the Medium and as my waist size diminished the adjustable belt worked as promised. The waist band stayed as tight as I wanted it. No matter how much weight I carried the pack shifted the weight to my hips and made the load seem light. The anti-gravity system worked great and there were times I was able to hike for hours on end with no pain or discomfort through the shoulders. That's a statement I can't make for any other pack I've owned. The pack shows a lot of wear after six months on the trail but everything still works like brand new. I love this pack and won't go back!
