OUR WINTER PURSUITS PACK

Move fast to and up your climb with the balanced weight, security, and comfort that the Prism brings to your Winter pursuits. Ideal for weekend or section hikes where frequent resupply points are available.

Charge headlong into the spectrum of winter’s white light with the pack built for alpine adventure. The Prism beckons ice climbers, mountaineers, alpinists, and backcountry skiers to think big and go deep. 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 low-profile lid. The hip belt provides two gear racks 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.

Perfect Pack for Adventures in the Mountains!
Great for carrying skis, ice tools, crampons, and everything else you need to have a skiing/climbing adventure in the mountains! Lightweight pack but super durable and supportable; comfortable to wear for many hours at a time!

My Favorite Piece of Outdoor Equipment Ever.
Simply wonderful. I love the fit, the comfort, the durability and functionality of this pack. I love the solid, shiftless way it carries weight close to my center of mass, and the minimalist aesthetic with nothing extra, nothing out of place.

Prism Pack is Great
This pack rubs an itch I have had for a simple, roomy pack for ski tours on a glacier. It has just the right amount of room for everything and carries really well. I can highly recommend it!

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…

Perfect climbing/skiing/mountain rescue pack

This is my first Hyperlite product and the the Prism Pack has exceeded my expectations! So far I've only used it for some alpine and snow/ice climbing, backcountry skiing including ski-carry in an A-frame and some mountain rescue training. Despite the low weight, it carries well. Loaded it up to ~45lbs with snow/ice gear, ropes, rescue equipment and part of a litter and it performed phenomenally!

The taper of the body of pack helps with movements while climbing. Only downside is the lack of a dedicated avy gear pocket but I knew that going into it - shovel and probe are now on the inside of the pack and with careful packing easily accessible.

Can't wait to use it for some multiday climbing trips into the Enchantments this year!

A good pack, but not amazing

Things I Like:

Weight: This pack is light. Its very light.

Durability: I shamelessly haul this pack over rocks, stumps, throw it down on sharp ice, and sit on it. It has held up beautifully. The build quality on this pack is outstanding. I cant overstate this.

Water Resistance: I really like having a pack that sheds water and keeps my equipment dry.

Internal visibility: The white interior really helps you find what you're looking for inside the pack.

Crampon Bag/Ice Features: The crampon bag is amazing. It can actually fit both my Petzl ski boot crampons AND my ski crampons. It lets you transition quickly without opening up your pack. The crampon bag also fits a nalgene perfectly. I also love all the ice axe attachment points.

Things I don't like:

No hydration tube slot: You have to run your hydration tube up out of the drawstring closure.

Load Adjustment: I dont like how every time you open the pack/remove the brain, you lose your load adjustment. I found that my pack becomes uneven and can cause some upper back pain unless you're really focused on keeping it adjusted properly.

Limited weight capability: I understand that this is a pack meant for quick alpine missions. If you're looking for a pack for a 3+ day backcountry ski trip, this might not be the one. I found that the low profile hip belt and minimal load adjustment straps made it uncomfortable to carry more than 30lbs over long distances. Its perfect for a tour or a ski mountaineering trip, but when the…
