Q36.5 Long Sleeve Base Layer A base layer is vital in winter, not just for trapping warmth, but also in dealing quickly with sweat; nothing worse than cresting a hard climb or powering into a headwind and feeling freezing from a build-up of moisture once effort levels reduce. And here the Q36.5 Long Sleeve 4 Plus Base Layer excels, keeping you both warm and dry. Built with a seamless tubular construction and advanced materials like Emana® yarn and hollow fibres, it actively helps your body generate and retain heat while wicking away sweat efficiently. Strategic mapping of breathability zones ensures the front provides maximum warmth, while the thinner back panel excels at moisture control, vital for keeping you dry during more intense winter training sessions. The result is an ultra-low volume layer that works perfectly under your winter jersey or jacket without adding bulk. Every detail of the Base Layer 4 is designed for high-performance riding in cold conditions. Its exceptional elasticity and low resistance to movement allow total freedom as you climb, sprint, or push through long endurance miles. By stimulating blood circulation in the upper skin layer and trapping your body heat, it creates a dynamic warmth that adapts to your effort level. Add in its push-pull moisture management and frictionless feel, and you’ve got a base layer that’s not just warm, it’s intelligent. Ride lighter, warmer, and drier, whatever the winter throws at you.
