Our Signature Ultralight.
Made for the days when you need to feel as light as air.
There's a point on a hot, long run where anything touching your skin starts to feel like too much the fabric, the seams, the weight of it all. The Ultralight exists for that exact moment. Engineered to disappear under your race pack, layer, or vest, it's built to be forgotten the second you put it on.
At just 100g, this is our lightest base layer yet stripped back to the essentials, with nothing extra to slow you down or hold in heat. Minimal by design, not by compromise.
Built for the hot ones.
Premium-grade fabric with moisture-wicking, quick-drying technology pulls sweat away from your skin and releases it fast, so you stay dry and regulated even when the miles and the temperature start stacking up.
A technical base layer, engineered for running.
Ultralight: 100g
Moisture-wicking, quick-drying premium fabric
Superior sweat absorption and evaporation
Designed to sit invisibly under race packs and layers
