Proprietary fabric development separates true race-level jerseys from standard performance wear dressed up with marketing language. Pas Normal Studios worked with Italian mills to create the 4D stretch-woven materials used in the Mechanism Pro Jersey, engineering polyamide and elastane blends that conform to the body through a full range of motion while maintaining structural integrity under sustained effort. The result feels closer to compression wear than a traditional cycling jersey, wrapping the torso in what the brand describes as a second-skin fit.

The construction uses structurally mapped fabric panels with variable stretch zones, placing compression where muscles benefit from support while allowing freedom where movement demands it. Laser-cut sleeves eliminate bulky hems, sitting close to the skin without cutting into the arms or riding up during extended efforts. The low-profile collar avoids restriction around the neck, and seam placement has been optimized to follow body contours rather than fighting them. A combination of stitched and bonded seams reduces bulk and potential chafe points throughout the garment.

Wind-tripping textured ridges run across the arms, shoulders, hips, and lower back, positioned to reduce aerodynamic drag in aggressive riding positions. The cut assumes a forward posture on the bike, which means the jersey performs at its best when you're committed to the drops rather than sitting upright. Three rear pockets sit higher than standard jerseys, keeping contents secure and accessible even when tucked into an aero position. The YKK zipper includes soft guards at both ends to prevent irritation.... Read More
