The running vests Scott Jurek, Anton Krupicka, Peter Bakwin designed for the 3.0 were incredibly successful, but the guys have been taking their adventures to very different places and needed their vests to go with them.
All our new vests come with Body Bottle 500’s and have a trekking pole carry system built into the front for on–the–go access, plus they all fit large smart phones in the front lower pocket. For easier sizing and a better fit, we've implemented the new Comfort Cinch technology on all of our 4.0 Vests and Vestas.
