1:1 is the realization of everything we know (so far) about how athletic performance can be optimized through apparel, footwear and equipment.
Think of 1:1 as the perfected, zero-tolerance, interface between athlete and gear. Gear designed and constructed to fit perfectly to the body in motion. Gear engineered to feel and perform as well at mile 26.2 or 100 as it does at mile 1. 1:1 is the perfect balance of anatomic fit, performance engineered materials and the personal interface between athlete and gear.
