The 2019 Castelli Viva Thermo Skully is a low bulk thermal cap designed to be worn under a cycling helmet to keep head and ears from feeling the chill.
Created in Castelli's warm and stretchy Thermoflex fabric, the minimal, flat-locked seams and raw-cut lower edge ensure the Viva Skully fits under your helmet with minimum bulk or irritation.
The fleecy interior is soft on the skin and also helps aid moisture transfer if you heat up on a climb to keep you dry, comfortable and warm throughout colder rides.
- Thermoflex is warm, soft and stretchy
- Raw cut edge lies flat and doesn't bunch under your helmet
- Flat-lock stitching
- Size Range - Uni-Size
