On days considered more cool than cold, a short sleeve base layer is all you need to give yourself an extra layer of warmth without having to worry about the added bulk of a vest or jacket. The company’s softest base layer to date, the Castelli Iride Seamless Short Sleeve Base Layer uses a new state-of-the art seamless knitting technology and a moisture-wicking blend of polypropylene, nylon, and lycra to keep your core warm while wicking moisture away from your skin.
A popular choice for performance base layers, polypropylene quickly transports moisture away from your skin. At this point, the Iride’s nylon layer takes over, transferring moisture outward where it evaporates, keeping you warm and dry. The Iride is also cut long at the waist to keep the base layer from riding up and out of your bibs.
The Castelli Iride Seamless Short Sleeve Base Layer is available in Black and comes in three sizes -- Small/Medium, Large/X-Large, and XX-Large. Like most Castelli clothing, the Iride base layer is designed to be form-fitting as the technical fabrics used to construct the garment work best when in close contact with your body. Be sure to check the sizing chart to ensure proper fit.
