What we think 

Co-designed with The Real Hiking Viking, a professional ‘hike-really-long-distances-really-quickly’, the ZERK 25 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. Mountainsmith 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 25 went through 4 iterations and over 5,000 miles of testing on the Wind River High Route, the Colorado Trail, The Tetons, and more.
