The Le Col Thermal Long Sleeve Base Layer is a lightweight next to skin base layer with fast wicking and extremely quick drying fabric. The Mesh construction ensures sweat moves fast from your body while locking in heat to keep your core temperature regulated. Designed to excel in conditions between 5-15C, the anti-bacterial, soft, and stretchy fabric ensures sublime comfort while keeping odours at bay. The low-profile seaming, ergonomically panelled construction ensures the base layer sits under your jersey or jacket as part of your layering system to maintain your performance through the off-season.
