A hyperlight short-sleeve base layer body-mapped with two types of open mesh for maximum airflow & moisture transfer during indoor training & the hottest racing conditions. he SUPERLe GER was developed primarily for two specific applications. The first addresses the demands of speed-focused riders who train & race indoors where the upper body layer needs be as light breathable & moisture wicking as possible. The second application is for the hottest outdoor racing conditions where the same considerations also apply but where a less revealing front mesh panel adds a touch of welcomed coverage while fully unzipped. WHEN/HOW TO USE IT: For indoor training the Skin Layer serves as your first & only top layer worn directly under the bib straps of your race shorts. For outdoor use pair it with the lightest race jersey in your wardrobe for a lightly compressive seamless first layer in the hottest environments. 89%PP 7%PA 4%EA
