2021 Zerk 40 Backpack

Countless hours, thousands of miles, a hundred beers, and one giant beard later and we are proud to introduce the ZERK 40. Co-designed with The Real Hiking Viking, a renowned thru-hiker with thousands of hiking miles under his belt, the ZERK 40 pack stands alone as the ideal combination of weight, durability, comfort, and accessibility.

Co-designed with The Real Hiking Viking, a professional hike-really-long-distances-really-quickly-er, the ZERK 40 was born out of a need for an ultralight pack that can withstand the thousands of miles per year that The Real Hiking Viking already covers. We wanted to make sure that it would allow him to go farther, to hike longer, and to work more efficiently on the trail.  Over the course of 2 years of development, the ZERK 40 went through 4 iterations and over 5,000 miles of testing on the Wind River High Rout, the Colorado Trail, The Tetons, and more.
