Castelli Mens Seamless SS Short Sleeve Base Layer

The Seamless SS Base Layer is designed to sit close to the skin, wick sweat quickly and provide targeted ventilation without the irritation of conventional seams. Rated for1630C, it’s a versatile base layer for mild through warm-weather riding.

• With the polypropylene inner layer, nylon outer layer and open mesh construction, this base layer was created to work with our race jerseys to move moisture away from your skin as quickly as possible. It obviously works well in moderate conditions, but we like it in colder conditions as well, under a long-sleeve base layer, because this is the best way to keep dry and maintain body temperature.
• 3 different mesh patterns to allow the most open mesh where you need the most ventilation
• Insanely soft for complete comfort
• Temperature: 22-28C / 71,6-82,4F
