Engineered for cold and cool days throughout all four seasons, the Ronhill Women's Tech Winter Half Zip Base Layer Top is a versatile thermal mid-layer that’s ideal for layering or wearing solo. Whether paired with a gilet or jacket or worn directly over a base layer, this half-zip is designed to provide warmth without bulk.

Crafted with innovative Prism fabric featuring a hexagonal grid, it captures and traps air for exceptional insulation in a slim, low-profile design. Its denier gradient technology wicks moisture swiftly from your skin to the fabric’s outer surface, keeping you dry and comfortable on any run. The long front zip allows for customisable ventilation, while reflective details on the front and back enhance visibility in low-light conditions. Warm, breathable, and adaptable, this mid-layer is perfect for any cold-weather activity.
