Nathan’s chief product tester, Dana “Mud ‘n’ Guts” Miller, is shooting for 20 finishes of the Wasatch 100. With 16 behind him, including 5 victories, he’s discovered that a lightweight hydration vest can cut down on the nausea sometimes caused by a waist pack. HPL #020 was designed to help Mud ‘n’ Guts survive another four Wasatch 100s. He suggests you use it on your next hundred-miler, whether it’s your first or your 25th.
