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!

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.

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

Great mountaineering pack

Comfortable, durable, lightweight… just love it.

Brain (top cover), would be great to be able to adjust hight (velcro side), depending on the amount of load inside.

But overall great backpack.
