Unanswered Question

Is the blue loop on the back above the straps load bearing? IE can I haul the bag using that blue loop?

Great for short climbs

  • Familiarity: I've put it through the wringer

I bought this pack for a week of hut to hut climbing in the Dolomites, but I also wanted to have another option for future trips besides my 75L Cilogear. I didn't test out attaching an axe or crampons, but I did manage to get a week's worth of gear in here without difficulty: helmet, harness, carabiners, water bottle, change of clothes, sleep clothes, sleeping bag liner, snacks, layers. I wasn't carrying the rope but it would've fit just fine with the lid. It was easy to get my stuff in and out and it carried the load well. I was able to cinch it down on days where I was leaving my things at the hut, however it did catch when I was squeezing through some cracks because I couldn't cinch it any tighter. It didn't snag, and a sudden storm came in and my things were dry inside. This bag is comfortable enough I'd take it on weekend backpacking trips.

I've never bought a hydration system before but after purchasing this pack I definitely need one, but don't know what type or size to get.

Hey Allison,

Adam, your Account Manager here! You can go with almost any hydration bladder with this pack. I would recommend checking out a Platypus bladder, Camelbak bladder or Osprey bladder. It should hold up to a 3L bladder but I will contact Black Diamond to confirm.

Please give me a call on my office line at 801-204-4580.

I'm wary of buying a zip top pack because I'm afraid my helmet won't fit inside on the approach. If you had everything inside your pack would you be able to fit a helmet inside?

So far so great!

  • Familiarity: I've used it once or twice and have initial impressions

Was looking for a light-weight day pack for spring/summer skiing and alpine pursuits. Used it on a recent (ski) summit of Hood, and was very impressed with the details of this pack--A-frame ski carry option, helmet carry, removable crampon straps, and ice axe storage--in an impressively lightweight package.

Haven't yet used the removable bivy pad (which was one of the reasons I bought it).

So far so great!
