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.
