I'm impressed with the Osprey
Stratos 36; it's the first I had heard of the pack, as my oldest son wanted a new pack for his birthday and this was on his list of likely candidates. I've had some experience with several other brands
(I learned the "get what you pay for" lesson long ago) and I was intrigued with the Osprey
as I read about it. We don't have a lot of shops to find packs in around my area - usually look at backpacking equipment when we do a trip to the zoo, etc. The build quality on this pack is VERY good. I was thoroughly impressed with the lightness of the pack as well, and the arched webbing that keeps the pack off the back is a great feature - no more soaking wet shirts
on a cold hike! We figure that he could easily do a two or three day hike with the pack, going mostly minimal on other things; just a ground sheet and a plastic sheet for cover, for instance, but with the ability to carry enough of everything else. I like that it also has a cover sheet, which is extremely useful in the rain, at the Olympics, that's almost a guarantee! Zippers are good quality and the warranty on the pack, if to be believed, makes it good for a lifetime of hiking
use. Now the only problem is how to get it off his back so that I can use it.
