Performance and Sweat Management in MTB: the case of the SIXS BT SBL Sleeveless Base Layer in Dryarn®

Managing thermoregulation during summer MTB rides is a fundamental technical challenge for cyclist comfort. Recently, QuiMTB Magazine analyzed the SIXS BT SBL technical sleeveless base layer, highlighting how its structure allows the skin to remain dry even under high thermal stress and scorching temperatures.

Why is this technology fundamental for cycling? The ability to manage body moisture does not depend solely on the garment’s design, but on the fiber used. The SIXS BT SBL sleeveless vest integrates Dryarn® technology, the microfiber that guarantees:

• Active Thermoregulation: it keeps the body’s microclimate constant, preventing overheating.

• Sweat Management: unlike traditional fabrics, Dryarn® expels moisture to the outside instead of absorbing it, preventing that wet feeling.

• Lightness and Comfort: the seamless structure eliminates chafing, a crucial advantage for those spending many hours in the saddle.
