BT SBL is the technical sleeveless base layer specifically designed for cycling (road or off-road).

It is the only product in the LIGHT BT V2 line developed with a primary cycling focus. It was created to perform in conditions of intense heat, high perspiration, and prolonged time in the saddle.

It is engineered to release excess body heat and keep the skin dry during summer activity.

40% lighter than the 4-Season line.

While pedaling, it delivers:

  • Constant dry feeling
  • Reduced sweat accumulation under the jersey

The Core Benefits

Maximum heat dispersion

The LIGHT BT V2 fabric is designed for intense heat and high perspiration. Its highly breathable structure promotes body heat dispersion and accelerates moisture transfer to the outside.

Ultralight construction

40% lighter than the 4-Season line, BT SBL is built for the hottest summer rides. The minimal structure reduces perceived weight and preserves full freedom of movement while pedaling.

Multi-zone construction

The multi-zone structure combines more compact areas with high-ventilation zones, placing breathability and stability exactly where needed. The result is a lightweight baselayer that maintains comfort and consistency during intense rides.
