Why use a base layer or seamless under garment?

We highly recommend that riders of all levels wear a base layer in all conditions. Our vast range of base layers are specifically designed and professionally tested to fulfill bodily comfort and performance needs at all times.

Base layers in summer?

Yes! A base layer is also necessary in the summer heat!

Our highly technical, seamless base layers are not just to keep you warm in the cold winter months. Even in the hottest of conditions, a base layer plays a very important role in comfort and performance.

Our seamless layers have a strong wicking capacity, drawing moisture away from your body, preventing sweat from building up on your skin.


Compression sportswear is designed to give added support in specific areas and aid circulation. Can be worn during exercise to prevent chafing and rashes, and post-exercise to ease muscle stiffness and quicken recovery time.
