Castelli Viva Thermo Skully
Sometimes simpler products are better, and nowhere is that more true than on this skully. Thin Thermoflex fabric is extremely warm yet provides excellent moisture management and easily fits under your helmet.
The raw-cut edges eliminate bulk under the straps. This really is perfection, simplified.
- Thermoflex is warm, soft and stretchy
- Flat-lock stitching
- Raw-cut edge lies flat and doesn’t bunch under helmet
