This ultra-lightweight, super stretchy base layer has been designed to provide a performance form fit and optimal moisture transfer and heat regulation during warm weather rides. The honeycomb structure of the knit not only wicks perspiration away from the skin but it also facilitates air movement between the jersey and base layer which speeds evaporation and cooling. Only 55 grams in a size medium.

\n\n

What sets this base layer apart from all the others is the use of woven Cocona particles from 37.5® Technology. Those amazing, little particles attract humidity and use your body heat to rapidly transfer perspiration from the interior to the exterior of the garment. This rapid transfer of moisture ensures a regulated body temperature and can increase athletic performance by as much as a 25% (results based on an independent University of Colorado study). This means you can ride longer and harder while staying cooler. Learn more at www.thirtysevenfive.com.
