When it comes to running in hot, humid conditions, the technical details matter. We obsessed down to the yarn level to develop this feather-light nylon blend differentiated by a unique grid structure that moves moisture away from the skin and up to the surface of the fabric. The Bluesign-certified material has an Ultraviolet Protection Factor of 30+ and is treated with coldblack to reduce heat absorption and an active>silver finish to reduce odors.
