The OS 02 is an overshirt in a technical woven fabric, and the fabric is what makes it work. Structured enough to hold a clean line, easy enough to wear from morning to night. It sits between a shirt and a jacket: wear it buttoned up on its own, or open over a T-shirt or a knit. A regular fit, with two buttoned chest pockets.
The 2.0 is built on what people told us about our previous overshirt, with a reworked fit and an improved fabric. It is made from the same fabric as the TP 02 Essence 2.0, so wear the two together as a suit or split them up across the rest of the wardrobe.
