ASRV x Outlast® Phase Change Headband - White Reflective Wings for Running, Cycling & Outdoor Sports | Moisture-Wicking & Temperature Regulation Headband

Product Description

The world’s first activewear built with NASA’s temperature regulating technology. Outlast® is a Certified Space Technology™ that creates an optimal comfort zone based on your unique microclimate. If you get too warm, Outlast® will absorb the excess heat, then as you cool down it will release that heat back to you. 4-way stretch fabric maximizes skin contact to get the most out of this technology while allowing total freedom of movement.
