Castelli has combined the Body Paint Tri Short with the Body paint Tri top to make the Castelli Body Paint Sr Tri Suit Sleeveless whose one-piece nearly seamless construction is incredibly comfortable and aerodynamic. Water is barely absorbed in the entire tri-suit which makes it perfect for the swim because you stay light in the water and you dry exceptionally quickly on the bike leg. The upper end is made with stretchy Velocity fabric which is not only highly aerodynamic it also dissipates body heat to help keep you cool. The lower portion, made with the Body Paint Tri fabric, compresses the legs to keep the cycling short portion in position whether you are riding your bike, running or swimming. The compression also helps to increase circulation which improves recovery time. The Sanremo front opening lies flat. When you need some cool air, it is easy to open the top while in motion. The leg gripper, with seams integrated into the fabric, keeps the shorts in place without pinching the legs, another factor that enhances comfort. The Kiss Tri seat pad has been designed specifically for comfort in the aero-position. The multi-layered padding in the right places makes it barely noticeable in the run and the swim.
