BT TS1L V2 is the short-sleeve technical base layer designed for use in conditions of intense heat, humidity, and high perspiration. It was developed with a primary focus on motorcycle use, engineered to perform under leather suits and protective technical gear, but it can also be used for cycling and outdoor activities.

It is designed to release excess body heat and keep the skin dry even during high-intensity use.

It is the lightest and most breathable base layer ever created by SIXS, evolved in the V2 version for greater anatomical precision and improved long-term stability.
