Pas Normal Studios
The Men’s PAS Mechanism Pro Sleeveless Baselayer is optimised for summer rides in warm temperatures. Built as part of the PAS collection, it is designed to sit close to the body and work as a lightweight foundation under a race-focused jersey, helping manage heat and comfort when the intensity rises.
The structure of the knitted fabric is developed by Pas Normal Studios and produced in Italy. Its proprietary construction stretches to the shape of the body, creating a close, adaptive fit that feels supportive without adding unnecessary bulk. The result is a sleeveless cycling baselayer built for warm-weather riding, high-output efforts, and a clean, low-profile feel under fast kit.
