Product technology


Coolite Mesh is for the extremist. This birdseye mesh fabric is ultra-light, super-wicking and insanely breathable. It’s a jacquard style knit with an extra measure of softness and loft to the fabric. You’ll feel that comfort against your skin along with a gentle compression effect from the spandex and polyester mix. The birdseye hole pattern keeps the cool air flowing even on the most scorching runs.


Tripure is a high tech nano fiber that delivers incredible comfort and performance. The Benchmarks are superior stretch and recovery and fined-tuned temperature regulation. Dries quickly, anti-microbial, static free and durable beyond all normal expectations. The humble waistband gets its 15 minutes of athletic fame.
