Castelli Lung Warmer

Castelli Lung Warmer. When biting cold makes it hard to take a deep breath, Castelli's 10M Lung Warmer delivers chest warming protection. Made with Windstopper 3 layer fabric, this piece covers your neck, lungs and air passages to allow you to breathe easily. The high cut neck keeps out chilling drafts and the tear away Velcro closure makes it easy to pull off when the race heats up.
