A mountain bike base layer is the foundation for your entire MTB clothing system. Mountain biking is an intense activity, and the right base layer keeps you warm whilst also keeping your temperature regulated - wicking sweat away from the body.

Base layers should fit tight to the skin, whilst also allowing the full flexibility of movement. They should be worn across all mountain bike disciplines - including downhill MTB and XC riding. These base layers are perfect for wearing alongside mountain bike jerseys & shorts.
