That emergency layer stuffed in your jersey pocket sees more use than anything else in your cycling wardrobe. The Pas Normal Studios Mechanism Stow Away Gilet earns its place there by compressing down to almost nothing while delivering genuine protection when conditions turn. Japanese nylon forms the shell, treated with a non-fluorinated DWR finish that sheds light rain and road spray without the environmental concerns of traditional water-repellent coatings. The PFC-free treatment degrades more easily in the environment and releases no lasting toxins, which matters if sustainability factors into your purchasing decisions.

The fabric itself uses a double weave construction where tightly interlaced yarns block wind while still allowing some breathability through the structure. This means core warmth on fast descents without that clammy, sauna feeling when you're working hard on a climb.

The mesh also reduces bulk when you compress the gilet for pocket storage.

Pas Normal Studios cuts this to their Mechanism fit, which runs close without restriction. The race-oriented silhouette layers smoothly over a jersey and stays put through position changes on the bike.
