The South Col 70 is a one-pack solution for mountaineering expeditions on the world's highest peaks. The flexible design and highly evolved compression system lets you add and remove components as well as shrink and expand the pack as needed. OutDry construction bonds a durable waterproof membrane to the main compartment so that your gear stays safe and dry in even the wettest conditions.

Waterproof backpacks have been a frequent customer request at Outdoor Gear Exchange for years, and it's easy to understand why. You don't want your stuff to get wet, and you don't want to have to cart along a pack cover all the time. But until now, waterproof backpacks have tended to fall into two categories: drybag-like, roll-top models with few to no external features; and fully-featured, seam-taped models that cost a fortune. That was until Mountain Hardwear applied their innovative OutDry technology to backpacks.

Originally found in backpacks and gloves, OutDry is a process that bonds laser-cut, one-piece waterproof membranes to fabric using heat and pressure. The result is seamless waterproof protection that requires no seam sealing or seam taping, and leaves no space between the outer fabric and waterproof membrane like sewn-in bladder-style waterproofing does. The result is a backpack with always-on waterproof protection that doesn't sacrifice any features and doesn't cost $800 like some previous waterproof backpacks did.
