This base layer has been designed to keep you both warm in cool conditions and cool in warm conditions. Woven with carbon fibers, Transfer–C™ fabric helps regulate body temperature while also transferring excess moisture away from your skin ensuring you stay comfortable through prolonged exertion. Carbon also reduces body odor. Ideal for layering with the appropriate seasonal jersey in temperatures between 35° - 85° F.

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 36 grams in a size medium. 

UPDATED FIT

Based on customer feedback, we’ve refined the fit to better align with our jersey sizing. We anticipate that you’ll be able to find a comfortable, barely-there fit by purchasing the same size you wear in our Summit or Ascent Jerseys.

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.
