Our Limited Edition Hardrocker Vest pays tribute to the epic Hardrock 100 Endurance Run held each year high up in the San Juan Mountains of Colorado. Just like this race and the indomitable runners who run it, the Hardrocker Vest is extra tough and extremely versatile. Based on our SJ Ultra Vest, this version adds 210T Taffeta nylon for extra strength, and two Body Bottle Plus bottles for all-day comfort (or two-day comfort for those racing the 48-hour cutoff time). The Wild and Tough Hardrocker Vest is a Limited Edition – it’s only sold on this website, only a few were made, and when they’re gone they’re gone.
