Stay cool in extreme heat with the Base Layer 0 Mesh Sleeveless, an ultra-light, breathable cycling layer
What Our Gearhead® Experts Are Saying:
"When the temperatures rise, this base layer is my go-to for staying cool and dry. The open-mesh design allows airflow to work with my body’s natural cooling system, wicking sweat away and letting it evaporate quickly. The seamless, second-skin fit eliminates chafing and bulk under my jersey, making it feel like I’m barely wearing a layer at all. Even in high humidity, it keeps me drier than riding without a base layer, making long, hot rides much more comfortable."
When the heat is relentless, the Q36.5 Base Layer 0 Mesh Sleeveless is an essential piece of our cycling kit. Designed for extreme temperatures and humidity, this ultra-light base layer works with our body´s natural cooling system to wick away moisture and accelerate evaporation, helping us stay dry and comfortable.
The seamless, tubular construction eliminates friction points and fits like a second skin, ensuring unrestricted movement. The open-mesh design enhances airflow, allowing heat to escape while keeping the jersey from sticking to damp skin. Whether we´re climbing in the midday sun or pushing hard on humid training rides, this base layer provides the breathability and moisture control we need to perform at our best.
