Maillot de Corps Sans Manches Mécanisme Pro pour Hommes

The Men's Mechanism Pro Sleeveless Base Layer is the race tier of the PNS base-layer range. Where the standard Sleeveless is a slim-fit polyester training piece, the Mechanism Pro is a compression-fit polyamide-and-elastane build that holds tight against the skin under a race jersey, wicks hard and dries fast between efforts. Sleeveless like its training sibling, but cut and constructed for race day — the base layer for the Mechanism end of the wardrobe.
