A very comfortable pack, even load to the max. I love all the adjustable waist belt and shoulder harness. Lots of pockets and lashing points that make it easy for me to carry me snowshoes and poles, a down sweater and jacket. A small compact alcohol or canister stove, dining set, pair of paints, sleeping pad, food for the day something like a Mountain House meal, a change of socks and long underwear, a water bottle or Water filter system, an 8'X8' tarp and hammock. Easly balanced to feel comfortable on my back even when climbing. I love the loops as well for ice axe use and for those that don't climb the hoops double as other attachment points for other stuff...the stretchable back pocket is where I stow my jacket or those must have essentials that require easy access. Waist belt has pockets for change, cell phone car keys etc...again easy access. The rain fly is already packed in its convent pouch. No more fiddling for one when it's dumping. A zippered top pocket has lots of storage.
I have had this pack for a year and figured I could give a full review. For the short day hikes, this pack works well. However, when you load it down (not hard in a pack this small) the hip suspension is very lacking. The pack has ample pockets, extra tie offs, a rain cover, and is durable. I did lots of scrambling in Tahoe and the pack shows no signs of wear. The vented back panel breathes well and the shoulder straps are comfortable.I used this pack on about 20 or so trips this summer. I did Mt Whitney in a day and found the suspension system was not stiff enough to carry the 30lb load comfortably for the time it took for the trip. Unfortunately, most pack manufacturers seem to skimp on the hip belts on packs these days.Keep the load light and the pack will work well.
I've had this pack for about a year now, and used it for a pretty wide variety of things. It carries my laptop around too and from work, lugs climbing gear along, and has spent over 400 miles on the trails during the field season. I also recently took it on an overnight trip out in Desolation. So after all this, here's what I think of it:Pros: Lightweight, comfy (for lighter loads), rain cover is the dopest, pretty good size for a wide variety of things, back doesn't buckle when not stuffed to the max. Osprey replaced a broken buckle within a few days of me shooting customer service an email.Cons: Hip belt can be uncomfortable with heavier loads, hydration bladder is pretty hard to slip inside. Definitely too expensive for what you get, unless you find it on sale.All in all, it's a pretty good pack. But for all the time I spent using it, I never really fell in love with it.
I can't speak to any extreme trekking, but for what I've put this pack through it's held up great and fit everything I've needed. Taken on 2 weeks through Peru and another 2 through Iceland I couldn't have asked for more.The zippers have never gotten stuck, and when I burnt through a strap on a baseboard heater Osprey had no problem replacing for me under their lifetime warranty.Also I've never had any airline question whether it would fit in the overhead
