Castelli Seamless Short Sleeve

The Castelli Seamless Base Layer represents Castelli's best and latest technology in a summer base garment. Seamless construction provides you with a fit so soft and natural it fells as if it is an extension of your body. It was developed and perfected with input from select Team Garmin riders.

The Seamless base uses a two material construction to acheive moisture managment with maximum ventilation. The inner layer next to your body is woven polypropylene which rapidly transports moisture away from your skin to keep you dry. This moisture is transferd outward to the outer layer which has an open mesh construction. This layer exposes the moisure it capture for quick evaporation. Being super vented, this outer mesh layer also provides massive amount of venting to keep you cool and helps regulate your body temperture. The perfect nexus of fabrics working in in tandem to keep you cool and dry.

The Seamless base uses 3 panels. the body and two arms. The only actual seams on the garment ot the flat stiching that joins these three panels. All panels are anatomically correvt to provide you with a tailored-like product that fits with out sag or bunching of material. One of the best base layers you can purchase.

To optimize moisture transport, Castelli uses a proven Polypro/Nylon fabric blend. Polypropylene is a popular choice for performance base layers, as the fabric's fibers quickly transport moisture away from your skin. Once the moisture has reached this point, nylon layer takes over, transferring the moisture outward to the surface of the garment to evaporate there, keeping you dry and comfortable. This base is made to work in warm conditions, but it can also be layered with a long sleeve base in cooler weather to maximize moisture wicking
