Compressport 3D Thermo Half-Zip Top Coming in hot to complete Compressport's baselayer range, the 3D Thermo Half-Zip Top is your essential ally when the temperature hits rock bottom - and beyond. Warmer and thicker than the 50g and 110g models, this undershirt offers the same high-performance, thermoregulating technologies with specific body mapping for added warmth in sensitive areas. Worn against the skin, the 3D weave not only evacuates sweat, but it also creates an air mattress to aid thermoregulation and ensure your core temperature stays stable in all situations. The stretchy, seamless design is durable and comfortable, fitting ergonomically to any body shape with zero irritation. The postural knit in the back helps you keep your shoulders straight as the hours build-up, while the fitted Raglan sleeves offer localised compression for extra support and freshness on the biceps and forearms.
