Did someone call for climate control?

This men's Burton Heavyweight X Base Layer Quarter-Zip will do the work. Highly breathable, heavyweight fleece keeps you cozy even on the coldest of mountain days, and four-way stretch works to give you all the flexibility you need for a solid day of riding. Bonus: you can still keep your friends close, thanks to the stink-resistant finish. (You're welcome for that one.)

FEATURES:

• Slim fit sits close to the body, with room for the garment to move with you.
• Heavyweight 300 Living Lining provides consistent temperature regulation without adding bulk or weight.
• Four-way stretch fabrication for enhanced mobility.
• Quick drying and highly breathable.
