What is Pas Normal Studios’ Mechanism Pro collection?

Mechanism Pro is engineered for aerodynamic performance. Pas Normal Studios’ most aerodynamic kit, built for the professional peloton. Proprietary 4D-stretchable fabrics and a second-skin fit deliver compression, breathability and efficiency. Free from friction and distraction. Made to make you faster.

How do Pas Normal Studios men’s sizes work?

Pas Normal Studios sizes its men’s cycling clothing by body measurements: chest around the fullest part, waist around the slimmest, plus hip and thigh, all in the size guide on this page (for example, M is 96–101 cm chest and 82–87 cm waist). The same chart covers PNS jerseys, bibs and jackets. PNS’s race-fit lines are cut close to the body for the riding position.

How should I care for Pas Normal Studios cycling clothing?

PNS recommends a pre-wash before first use, then washing inside out with zips closed, on a gentle 30 °C cycle with low spin and a non-bio detergent. No bleach, fabric softener, tumble dryer or hot iron: let it air dry, and don’t mix light and dark colours. The garment label is the final reference.
