It's been a good early season in the snow and I've used my Kamber several times now. Over the past few years I've used Black Diamond packs and last year the Patagonia Snow Drifter. I have to say that thus far the Kamber is the most comfortable pack I've worn ski touring. It hugs your back and adjustments are easy to make while climbing and loaded up. It can carry all my essential gear and if I pack it just right I can even fit my full frame camera in (on the descents only, I carry it on my chest while climbing). The helmet sling works great and you can carry the helmet on top of the bag or on the back. I've already got a cut in the helmet sling material but it still works great and has not gotten any larger in size. My favorite features, of this pack, are the hidden hydration tube sleeve in the right shoulder strap and the massive/easy to access hip pockets. I drink a ton of water and appreciate the separate hydration compartment and routing into the shoulder strap. The hip pockets, on the waist strap, are flat out fantastic. I put my skin track snacks in there and they are easy to reach and open with gloves on. Tool organization is easy and I like that there is enough room that skins can fit in there too.
One suggestion would be to make the top zipper pull/zipper of the tool pocket a different color that stands out, so in case of an emergency you or someone else can look at your pack and know exactly where your avy tools are.
Needless to say I sold off all my other packs and am looking at the adding the next size up to carry all my camera gear.
