Q36.5 Sleeveless Mesh Base Layer The Q36.5 Sleeveless Mesh Base Layer features an open mesh structure and tubular seamless construction that work in harmony to wick sweat away from your skin, allowing it to evaporate rapidly and create a cooling effect. Unlike traditional base layers, the Q36.5 Zero doesn’t just sit against your skin; it actively regulates your temperature by maintaining a microclimate between your body and jersey. This means less overheating, less discomfort, and more focus on what matters: your ride. The varying mesh densities are strategically placed to match your body’s sweat zones, so you stay drier where it counts most. But comfort isn’t just about cooling; it’s about feeling unrestricted. The ultra-stretchable, frictionless fit moves with you, eliminating hot spots and chafing even on long rides. As the lightest base layer in Q36.5’s collection, it’s designed to disappear under your jersey, letting you forget about your kit and concentrate on the road ahead.
