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.
