Rated 5 out of 5 by from The Most Perfect Daypack I bought this pack last season. I had bought one of their smaller running packs, but they run small. When I took it back I tried this on. It had more room for gear yet tightened down so your pack doesn't swing/flop around. If you like to hike light and fast this pack is for you. They have a larger model but this pack fits everything I need for a day hike or overnight, when in warmer weather. It's made well, using light materials. The storage pockets up front mean you rarely have to take it off until you get to your stop. The pack weight is really evenly distributed with the wide shoulder straps. It has trekking pole holders. Two side large water bottle holders and inner bladder holder, and two pockets for smaller soft bladders up from. Perfect for changing up your water storage for hiking/trail running/climbing. I highly recommend it.

Rated 5 out of 5 by from Great product I hesitated in purchasing this pack because it doesn't have a waist belt. I thought that when the pack was full it would bounce around too much or be too heavy on my shoulders. Neither happened. I filled it up as full as it could get and took it for a test run. While running I was able to snug up the straps and the pack stayed in place. I couldn't be happier.

Is the bag waterproof?
