BEST PACK IVE EVER OWNED
Ice climbing—perfect. Backcountry skiing—perfect. Overnight backcountry missions—perfect. Ski Patrol—perfect!!
I genuinely feel unstoppable with this pack, bombproof, so comfortable, doesn’t get in my way when leading ice, and always seems to meet my needs.

Awesome ice climbing pack
I bought this to replace my old ice climbing/winter hiking pack. After using it quite a bit this winter, I absolutely LOVE it. I bought one for my son as well to replace a less than ideal pack.

The best pack I've ever had for ice climbing.
I used this pack for this ice season and I absolutely love it. The crampon pocket works fantastic as well as the tool mounting.
