Product Reviews and Questions
Best alpine ice pack
Have put this pack through ringer for 3 years now and it has held up. Most comfortable pack I've owned whether it's weighed down for the approach or cinched down for the climb.
Prism 40
The best pack hands down for ice and alpine climbing! Been using my own for a couple of years now, and bought one for Christmas for my daughter.
This is HMG pack #6 for my family!
Almost perfect ice climbing pack
I liked everything about this pack (compared to other “ice climbing pack designs”. Only wish it had a larger top pocket to accommodate extra mitts, first aid kit, beacon.
Best light weight simplistic minimalist pack out there
Great pack, really ticks all the boxes. Light weight, simplistic, minimalistic, super durable, VERY comfortable. great features. I measured my torso and went with a Medium. Should have got a size small unfortunately. But I will just have to get by
