A simply great pack

A simply great pack

A very handsome pack, with great customization and I love the comfort with a heavy daypack loads, be it snowshoes, crampons, axes, an accidentally frozen 2L water bladder, just whatever I need to bring.

Great pack for alpine climbing!

  • Familiarity: I've used it several times

This is a great pack that I purchased for a light and fast trip up California's Mt Whitney Mountaineering Route. I loved it for that trip and have used it for a few other trips since. Definitely has some great features without any extra bulk. Only downside I saw was that it was slightly floppy when only about 1/2 full and I couldn't minimize the excess space as much as I like. However the 35 is always an option over the 50 and I think it deserves the full 5 stars.

Besides its primary use, would this pack...

Besides its primary use, would this pack be adequate for a 2-3 day winter backpacking trip? Say, leaving the ice axe and crampons at home and swapping them for a 4-season tent, sleeping bag, and snowshoes?

If not, what would be a good pack to double duty between alpine use and 2-3 winter backpack use?


To best answer your question we'd need a little more information about your set up. As the best I'd be able to do is to say that for some this could work on a 2-3 day winter backpacking trip if you have a 1 or 2 person 4-season tent and a sleeping bag that is uber compressible.

If you have a 3 or 4 person 4-season tent then I'd rule this out for a 2-3 day adventure. But I'm keeping in mind that you're packing minimally for this trip and not bringing the kitchen sink with you.

For alternative pack suggestions, could you provide us some details about your winter backpacking style and equipment? Feel free to call in at 800.409.4502 and ask for me (Jared D. at extension 4055). I'd be more than happy to walk through the options that will fit your style best.
