Running is such a simple act and this is all the impressive technology behind that simplicity. We want to bring you the latest technical fabrics and innovations in running apparel so you can float over a rocky mountain trail or crack a new personal best on the roads just outside your doorway. When your gear is great, it disappears and you’re free to fly.

The flex is in the spiral yarn. This configuration gives the fabric a built-in mechanical stretch that goes to all 360 degrees of adventure. Thanks to this technology, the fabric will stretch and recover without using heavier water-absorbing elastics like Spandex. Upshot: outstanding breathability, abrasion resistance and a softer feel against your skin. All this at 40% the weight of the old school stretchy stuff. PrimeFlex is both eco and techno. The fabric is partially made from a corn-based material that uses less water during processing. There’s comfort from mile one to mile one hundred.

Twill is a timeless casual fabric. Toray’s FlexTwill takes this classic and injects some athletic DNA. The fabric has a mechanical stretch and the ability to spring back and recover its shape even with extensive torsion. Unlike spandex, it doesn’t wear out like a rubber band or soak up water like a sponge. FlexTwill is big on durability, abrasion resistance and quick-dry capability. This is a crossover hybrid twill you can run, chill and live large in.

This fabric mix scores high on breathability and lightweight design. The TENCEL blend amplifies the moisture wicking skills and odor resistance. TENCEL is a traceable and sustainable fabric made from eucalyptus wood pulp. That gives you a softer feel against the skin and a gentler effect on the planet. Non-toxic chemicals and solvents are used when creating the fabric. Think premium pima cotton alloyed with a high-performance synthetic.

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.

Honeycomb structures show up in designs for rockets, audio speakers and telescope mirrors. We developed this honeycomb fabric for its mix of breathability and excellent mid-level compression. When you stretch this spandex and polyester hex fabric, it actually opens up the airflow around the edges of each honeycomb. Shasta gives you four way stretch, moisture wicking and an anti-odor treatment. This is our most versatile baseliner fabric – a jack of all trails and roads.

Featured in the base liner: SHASTA HX FULL LENGTH

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.
