Taking track performance to another level: meet the Supersonic undersuit. It’s a 3D round-knitted one-piece base layer that is purpose-built to be worn under your race leathers. 

Thanks to the use of the unique, flexible, and ultra-lightweight DRYARN® fabric, climate control within your race leathers will be second to none. You will stay dry and comfortable, lap after lap, even in the hottest of track conditions.

Adding to its impressive resume of features, it’s also hypoallergenic, meaning it limits the multiplication of bacteria and reduces odor along the way.
