Move fast to and up your climb with the balanced weight, security, and comfort that the Prism brings to your winter pursuits.

Designed to meet at the intersection of speed, weight, security, and comfort, this top-loading pack features an extendable drawstring closure and an adjustable, removable floating lid. The hip belt provides two gear loops and two ice clipper slots, but is removable when not required for the task at hand, or when wearing a climbing harness. Climbers can store a rope under the lid, glacier adventurers can store their wands in the side pockets, and backcountry skiers can depend on the A-frame carry when they’re on foot marching up the steep stuff.

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

Guide
Hi, I am an Ifmga guide living and working in patagonia, chalten for 20 years. I guide all the most challenging climbs in the are as fitz Roy. This is my first year with your pack an i really like it.
My suggestion is related to the hip belt. I know it's removable but will be nice if it camps with a thin strap belt to climb with. Thanks
well designed and well backed
I have high expectations fort this pack, I'm sure it will out perform its peers within the price point. I was really impressed with the customer service I received from HMG after I wanted to return my beat up porter. Partial refund, great knowledge of which pack I was needing regardless of what I was wanting. Thankyou Sarah for being patient with my back and forth emails!
I really want to love this pack
There are many, many good things about this pack. There's the general perks of HMG gear such as incredibly sturdy, lightweight and waterproof. On its maiden voyage, I had to emergency bivy with this pack and it kept my things dry and helped keep my body off the ground.
I love the lid, it's the reason why I chose this pack over the Porter or Ice Pack, though it could stand to be a little roomier. The pack's layout worked well while wearing a harness, and the daisy chains and crampon pouch were so so helpful. I also love the fact that the side compression straps buckle for both; my other climbing pack doesn't have this option, which makes this pack much more versatile with strapping ropes, pads and boots to the pack. I'm also so glad that the ice axe carry loop is on the side of the pack, and not in the MIDDLE like the Southwest (seriously, why is that tool loop there??? Borderline unuseable)
The one major flaw of this pack, which I know is a detriment to most ultralight packs, is its comfortability with weight. It's advertised load capacity says 50lbs, but on a three day assault of Glacier Peak, 36lbs carrying into camp did not carry as comfortably as I thought it would, and I had much more back soreness and shoulder pain than my companions with their much heavier bulky backpacking packs. Even on summit day, when my pack couldn't have been more than maybe 15-18lbs, I had what felt like consistent pinching in my shoulders.
On the way down back to the trailhead, even though…
