Nice little pack
The cloudwalker is a great pack for day hikes, around town use, even ultralight overnighters. The quality of the materials and stitching is top notch. Just what I have come to expect from camelbak. The zippered pocket in the front has a nice little organizer and the main pocket is surprisingly roomy for such a small pack. It has a flexible back panel that offer a little support, but if you stuff it the pack will deform and will no longer sit flat on your back. The 'frame sheet' is flexible enough that you can actually fold the pack in half to pack it. It is comfortable for me at a weight of around 15 lbs total. This pack has been dropped, thrown, folded and smashed, dragged, filled to the brim with geodes, and submerged, and is still no worse for wear other than a little tear on the mesh bottle pocket.
I really only have one complaint about the cloudwalker. The new generation (pictured here in black. The blue one in the detail view is a different generation) doesn't have a waistbelt. If it had one, I would give it 5 stars for versatility and value because at $60 you are buying a $25 bladder and a nice pack for $35.
