Sixs BT STXL R V2 Black Carbon Full-Face Undersuit

BT STXL R V2 is the full-body undersuit developed for working under leather suits and technical protective clothing.

It's part of the LIGHT BT V2 line: the lightest and most breathable platform ever created by SIXS, designed for intense heat, humidity, and high sweating. It's engineered to release body heat.

The V2 version integrates a new, more resistant yarn, specifically developed to improve durability and hold over time in the areas of greatest stress.

40% lighter than the 4-Season line.

Key Points:

• Full-body undersuit designed for intensive motorcycle use
• Dispels heat and sweat in extreme heat conditions
• New, more resistant yarn in critical rubbing areas
• Multi-zone construction for ventilation and durability targeted
• 100% Made in Italy

Designed for motorcycle use
This undersuit was created for:

• Racing and sports driving
• Summer tourism
• Long distances in hot conditions

The close-fitting construction prevents creases and bunching under the suit, reducing pressure points and improving stability while riding.
Multi-zone technical construction
The building integrates several functional areas:

• Compact mesh: Positioned in areas of greatest friction to increase resistance.
• Breathable mesh zones: Placed in central sweating areas to promote ventilation and heat dispersion.
• Elastic containment structures: They guarantee an anatomical fit and stability while driving.

The new, more tenacious yarn improves durability in stressed areas without compromising lightness and breathability.

Evolution V2: stronger, more stable
Compared to the previous version:

• More resistant yarn in critical areas
• Optimized anatomical fitting
• More precise study of the rubbing areas
• Redesigned elastic band: higher at the front and lower at the back, to follow the posture in the riding position
• Better structural strength over time

The new configuration of the waistband is designed to accompany the motorcycle position, maintaining stability without creating pressure on the abdomen and ensuring continuity in the lumbar area.
Breathability remains the primary DNA of the LIGHT BT V2 line: the garment promotes the expulsion of humidity, reducing the sensation of wetness and sudden chills during stops.

Feeling in use
In driving it translates to:

• Constant dry sensation
• Reducing friction under the suit
• Greater comfort on long journeys
• Stability under protection

BT STXL R V2 is the most advanced summer technical undersuit for the motorcycle segment within the LIGHT BT V2 platform.
