Castelli Pro Thermal Skully

Made for warmth with excellent wicking while minimizing bulk under your helmet. This simple helmet liner has a raw-cut edge so it doesn't interfere with the straps or helmet cage, while the Thermoflex fabric is surprisingly warm and wicks away moisture.

- Thermoflex is warm, soft and stretchy
- Flat-lock stitching
- Contoured to cover ears
- Raw-cut edge lies flat and doesn't bunch under helmet
- Reflective detailing on back
