Lightweight motorcycle undersuit
BT STXL R V2 is the full undersuit developed to perform under leather suits and protective technical gear.
It belongs to the LIGHT BT V2 line: the lightest and most breathable platform ever created by SIXS, designed for intense heat, humidity, and high perspiration. It is engineered to release the body’s excess heat.
The V2 version integrates a new reinforced yarn, specifically developed to improve durability and long-term resistance in high-stress areas.
40% lighter than the 4-Season line.
While riding, it translates into:
- Constant dry feeling
- Reduced friction under the suit
- Greater comfort during long rides
- Stability under protectors
BT STXL R V2 is the most advanced summer technical undersuit for the motorcycle segment within the LIGHT BT V2 platform.
