The Endurance Jersey from Oakley tells you a lot just from its name. It's developed for those long days on the road where you want a comfortable fit as well as staying cooler when it's hot enough to create a mirage just above the surface of the asphalt. This jersey relies on a regular fit and uses refined materials throughout, such as Oakley's O-Stretch fabric conspiring with mesh panels in strategic areas to keep you cooler on summer rides.The polyester/Elastane material is exceptionally breathable and wicks perspiration from your skin where it transfers it to the surface to dry quickly so you stay cooler and drier when the tempo and temps spike on those warmer group rides. Other details worth a mention are an aerodynamic fabric on the sleeves, a reflective waistband, and transparent reflective accents on the sleeves for increased visibility in low light.The Endurance Jersey is available in 3 colors: Red Line, Blackout, and Balsam and in 6 sizes between XSmall and XXLarge.
