PASメカニズムプロノースリーブベースレイヤー

The Mechanism Pro Sleeveless Baselayer is Pas Normal Studios' minimalist summer foundation for high-output riding and running in hot conditions. Designed as the lightest base-layer position in the PNS range, this sleeveless construction prioritizes airflow and moisture transfer when temperatures climb and efforts intensify. Worn under a jersey or on its own during interval sessions, the Mechanism Pro delivers breathable next-to-skin comfort without excess fabric across the shoulders and arms.
