The running vests Scott Jurek, Anton Krupicka and Peter Bakwin designed were incredibly successful, but the boys thought of some great improvements for Signature Series 2.0. For additional durability, we switched from Cuben Fiber to Silnylon 66, beefed up all the mesh and bungy cords, and added edge binding to the stretch pockets on all three vests. For easier sizing and a better fit, we added lateral adjustment straps on Scott’s and Peter’s vests. Those two vests now have a third zipper for easier access to an optional internal bladder. Anton's vest is more streamlined without the pockets at the bottom of the main compartment. And finally, everything has been updated with our new color and logo.
