It’s OK to run in cotton. With its signature MothTech™ holes for increased ventilation and cooling, this is our go-to top for everyday mileage and training.

- MothTech™ 
Our MothTech™ program is inspired by the “moth” holes found on true vintage cotton t-shirts. However, we’ve taken this aesthetic predilection and made it a highly functional feature. “Moth” holes are body-mapped on organic combed cotton for strategic ventilation with a special focus on the areas of the upper body that produce the most heat, creating a unique cooling system. Breathable and versatile, these shirts only wear better as they age.
