Renowned mountaineer George Mallory followed the Rongbuk Glacier in Tibet while looking for routes to Mount Everest in 1921. In 80 years, the Rongbuk has shrunk by more than 300 vertical feet across the entire glacier.

The Rongbuk 28 features a smaller outer pocket with just a strap and buckle over the top for those things you need to access quickly, and larger middle compartment with a zippered top to secure items, and a large main compartment for clothing or other bulkier gear. Inside the main compartment is a sleeve that can hold a hydration system, a tablet or small laptop. A fleece lined garage for your sunglasses or cell phone is at the top of the pack.
