Yup - with the big pockets!

When we designed our 4400 Ice Pack, we thought K2, the Latoks, and Alaska’s Hayes Range: places where weight can make or break an expedition. This pack is perfect for the rugged alpine climber or ski touring maniac. It's streamlined to carry exactly what you need and nothing more for multiple days in the most extreme or high altitude environments. Like all of our 70-liter packs, this ultralight pack has an additional plastic frame sheet for added load carrying capacity. Made from 100% waterproof Dyneema® Composite Fabrics (formerly Cuben Fiber), the 4400 Ice Pack is highly durable and weatherproof. Fortify your pack with our Stuff Sacks for a waterproof finish.
