The Women's On/Off Base Layer LS Top is a high-performance, long-sleeved base layer designed to support female athletes through every phase of their training. Whether you're powering uphill or recovering on the descent, this top intelligently adapts to your intensity with Compressport’s proprietary On/Off technology.
This innovative fabric features alveoli that open and close based on your breathing and movement, offering dynamic ventilation when you need it and insulation when you don’t. The women-specific body-mapping ensures enhanced protection in sensitive zones, while the seamless microfiber construction delivers unmatched softness and zero chafing.
Ideal for running, trail, triathlon, or any outdoor sport, this base layer also integrates Spin Control technology to support posture and reduce fatigue. Lightweight, antibacterial, and quick-drying, it’s the ultimate fusion of comfort and performance.
