Compressport On/Off Base Layer Long Sleeve Men's Top

High-tech, long-sleeved baselayer with body-mapped thermoregulation for optimal performance and comfort in cold conditions.

Choosing the right base layer in the middle of winter can be the difference between staying out and cutting your training short. The On/Off Base Layer Long Sleeve Top Compressport has been created using the brand's unique On/Off technology, making it ideal for use during all outdoor sports. This exceptional technology breathes with you to regulate ventilation and protection depending on the intensity of your workout session. As your training intensifies, your chest expands to take in oxygen. When this happens, the alveoli in the fabric open up to reduce compression and increase breathability, allowing for improved comfort that enables you to continue without distractions. As your effort decreases, the alveoli close again to provide you with warmth and protection. Perforations throughout the garment vary in size depending on the area of the torso. Larger openings in less sensitive zones, such as the ribcage, while smaller ones can be found around the neck and wrists. This clever body mapping allows for quick-drying, high-performance thermoregulation, keeping your core temperature steady no matter your effort or the conditions. The close ergo-fit has been designed to support this high-tech effect. It leaves minimal space for air draughts and ensures maximum warmth for your outdoor workout. The On/Off Base Layer LS Top also features Compressport's signature Spin Control technology woven into the back to help you maintain good posture. A seamless microfibre sits comfortably against the skin, giving a chafe-free finish while natural anti-bacterial properties combat odours and irritation. Lastly, the round neck adapts to your morphology for optimal comfort and raglan sleeves free up the shoulder for full freedom of movement.
