I bought this pack after extensively researching "ultralight" pack options... I went with the large as I like the flexibility of being able to pack in a few extra days worth of food, on an extended outing.

I've only been out on a few hikes with this pack so far, but it's done absolutely everything I imagined it would.  Very comfortable, very light.  The 360-degree
compression straps/lines are nice.  I didn't think I'd like the roll top so much, but I do... really, it's great!

Awesome pack by an awesome company.  Thanks!
