Compressport On/Off Thin Headband The On/Off Thin Headband is an ultralight technical accessory engineered for high-intensity training and racing in warm conditions. Built with "On/Off" interactive fibers, this headband breathes with you, opening its pores to evacuate heat when you are pushing hard and closing them to protect against chills during lower-intensity phases or descents. Technical Performance Features On/Off Interactive Fiber: The unique weave features thousands of alveoli (tiny pores) that open to provide maximum aeration during peak exertion and contract to retain light warmth when your heart rate drops. Hydrophobic Sweat Management: The fibers are designed to wick moisture away instantly rather than absorbing it. This prevents the headband from becoming heavy, waterlogged, or uncomfortable during long sessions. Seamless Ergonomic Fit: Constructed without seams or elastic bands, the headband conforms to the shape of the head without applying excessive pressure, eliminating headaches and "pressure marks." Ultralight & Compact: At approximately 15g, the thin profile is designed to be worn comfortably under cycling or climbing helmets without interfering with fit or safety. Ultra-Stretch Fabric: The highly elastic weave ensures a secure, "one-size-fits-most" fit that stays in place during vigorous movement and high winds.
