We all know you lose a lot of heat through your head, which is not ideal when you're riding through the chill of an awesome Winter or Spring  day. The lightweight Defend Skull Cap fits seamlessly under your favourite helmet, while its insulated fabric helps help regulate heat and keep you warm and dry. Warmer riders ride longer.

• Lightweight, insulated fabric actively regulates heat to keep you warm and dry
• Minimalist design fits under most helmets
