Unrestricted Innovation
Simply put, the Propulsion Harness™ (patent pending) moves with you, not against you. Unlike traditional shoulder straps, the Propulsion Harness works in harmony with the back and forth movement of your shoulders and upper torso, preventing the pack from "riding up" or swaying back and forth. And thank to two inches of frictionless travel, from 2-way configuration, each shoulder strap moves independently, offering unmatched freedom of movement without reducing pack stability.
David Horton
In the summer of 2005, legendary ultrarunner David Horton (or as Nathan calls him HPL Experiment #063) set out from the Mexican border, headed to Canada on the Pacific Coast Trail. His goal: to set a new speed record of 63 days. Nathan designed several custom products to help Dave achieve his dream. The HPL #063, named for Dave, is one of those products Nathan thought others could use to achieve their own dreams.
