We thought K2, the Latoks and Alaska’s Hayes Range (places where weight really makes a difference) when we honed our 4400 Ice Pack for the rugged alpine climber and ski touring maniac.
We streamlined this minimalist expedition backpack to carry exactly what you need and nothing more for multiple days in the most extreme or high altitude environments. It’s large enough for the traverse in, yet minimalist and light enough for the day on the wall.
Like all of our 70-liter packs, this ultralight pack has 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.
