Iron Horse Thermal Pro Half-Zip Skivvy
Experience elite warmth without bulk with the Iron Horse Thermal Pro Half-Zip Skivvy—engineered for jockeys and riders who demand superior performance during cold track mornings and winter training sessions.
Fleece-Lined Thermal Protection
Soft fleece interior lining traps body heat and provides essential warmth during cold track starts and early morning rides. Stay comfortable in frigid conditions without the bulk that restricts movement or interferes with your silks.
4-Way Stretch Performance Fabric
Advanced 4-way stretch construction moves with your body through every motion—from mounting to racing position. The fabric stretches horizontally and vertically, ensuring unrestricted movement and a sleek, athletic fit that never binds or bunches.
Half-Zip Ventilation Control
Strategic half-zip design allows instant temperature regulation. Zip up for maximum warmth during cold starts, then adjust ventilation as your body heats up during intense work. The smooth zipper operates easily even with gloved hands.
Sleek Base Layer Design
Low-profile construction layers seamlessly under racing silks, show jackets, or vests without adding bulk. The fitted silhouette maintains a professional appearance while delivering the warmth you need for peak performance.
