My pal James just let me know he just launched a second Kickstarter for his NanoDri Undershirts.
As a refresher, NanoDri Undershirts & Shirts are designed with two very lightweight layers of fabric, to prevent sweat through on those who sweat more heavily.
The first layer is optimized for wicking/transport to pull sweat from the skin and distribute it across the layer’s surface. The second layer is optimized for moisture blocking, to prevent the sweat from getting to the outer layer.
