I, and most every guide I've had, would *not* recommend using a camelback while skinning. Unless you can be certain that conditions will be above freezing, camelbacks have a nasty habit of freezing while skinning leaving you without water. Not a big deal when you're just one ski away, but annoying. Hydrating at each transition will be enough if done regularly.
As for the micropack -- a bunch of external straps like that make me nervous while riding lifts. No matter how low profile, straps can get tangled. This was beaten into our heads during lift evac practice and lecture last week. One common cause for people failing to unload probably is gear snagged on a chair. There is a reason why in-bounds focused packs typically havea very smooth back. Example:
That is a nice pack and agree with the concern of getting loops caught on a chair lift, but the entire reason why I want the pack is for when I'm NOT riding the chair lift. I only want it for skinning and will probably also use it now and again when I go hiking with my wife. I have to admit I do like this pack and
it is definitely a contender.
I could possibly use it for coaching (and riding the lift) instead of the godawful ones we have.
I am used to going up the lift with backpacks but they are usually full of timing gear, brushes, and spare drill batteries and have loops and tethers all over the frickin place. Not to mention adds about 6 inches to my girth and is why I typically take the pack off and keep it on my lap for the ride up.
With regards to the freezing camelbak tube, it's a matter of trade offs; risk a freezing tube, risk a freezing bottle, risk tripping via ski pole, risk slowing down to take off pack to get to water etc. If I was going on a backcountry adventure, the freezing would be more concerning, but even on telemark gear, I can get down my home mountain where I'm doing this in just a few minutes. I have used a camelbak with a different pack a few times while skinning up and it did freeze on me once. After that I was more careful full about things and would make sure to keep the water moving and not in the tube. I am considering getting a insulating sleeve for it and as
@elemmac points out, there are some things to do to help prevent this.
I really don't like carrying a pack at all while skiing and avoid it like the plague. Aside from skinning up, I don't see myself carrying one aside from coaching (and I should consider that with this purchase). Nor (at least at this point) do I see myself doing any skinning outside of my home mountain now and again to stay in shape (once I get in shape).
Thanks,
