The Cramster HyperFlex Base Layer – Upper is a long-sleeve riding base layer made from 92% Polyamide and 08% Elastane, suited to hot and humid conditions. Its 4-way stretch gives freedom of movement and durability on rides, and anti-microbial properties help eliminate or inhibit the growth of microbes and bacteria while preventing sweat odours from building up. Moisture-wicking fabric with specialised capillaries pulls moisture away from the skin, and the 100% breathable fabric keeps the wearer comfortable during strenuous activity. It prevents visible sweat patches and regulates body temperature, while seamless knitting eliminates chafing from seam stitching. It comes in black with a crew neck, raglan sleeves and a white Cramster logo on the chest, and carries a warranty of 6 months from the date of purchase/delivery.
