The Compressport Pro Racing Singlet was developed with racing in mind, as it's an ultra-light, high-quality microfiber top with integral ventilation technology for maximum performance in high temperatures. The lightweight material makes this one of the lightest tank tops to date, thanks to thin ventilation inserts on the body and sleeves, underarm mesh and special ventilation channels at the front and back. Soft microfiber and fleece seams mean no chafing marks. Extremely easy - Maximum ventilation and wicking - No irritation - Composition: 92% polyamide, 8% elastane - Weight: 53 g
