Chester was designed by Mike Story, the creator of the original 4SRT chest harness. With alternating loops that accommodate multiple height preferences, Chester can be adjusted to your exact requirements. Made of lightweight and durable nylon webbing, Chester is more comfortable and a significant upgrade from using makeshift ropes and carabiners to aid SRS climbing. Plus, it looks cool. Attach a Magneato for easy connection to your rope runner while climbing.
