Minimalist meets performance in this tight with extreme-comfort Thermoflex fabric along with our fleeced Nano Flex stretch-woven lower leg for splash protection. Especially good when you don't want a deep-winter tight.
- Thermoflex fabric from knee to waist for warmth and comfort
- Nano Flex stretch-woven fabric with brushed fleece inside at lower leg for splash protection from wet roads
- KISS Air2 seat pad
- Mesh bib straps
- Zipperless ankle to reduce bulk inside shoecovers
- Reflective inserts on thighs for visibility on back and sides
The ideal tight for most of your winter riding, the Velocissimo is focused on comfort for riding in mild to cool conditions.
We've used our Thermoflex fabric for most of the tight. It's not our warmest fabric, nor does it repel water like Nano Flex, but it is the softest, stretchiest winter tight fabric. The comfort is immediate and lasting. For the lower leg from just below the knee, we switch to our Nano Flex fleeced stretch-woven fabric that's both warm and highly water repellent for protection against spray coming off wet roads. It's also highly stretchy, and we leave a raw edge so we can construct the ankles without zippers while making sure the tight remains easy to put on and take off. The Kiss Air2 seat pad and mesh bibs keep your bum and upper body happy, while large reflective detailing keeps you visible.

- Waist: measure horizontally around the natural waistline, keeping the tape slightly loose.
- Hips: measure horizontally around the fullest part of the hips with feet together.
- Inside leg: measure a well-fitting pair of trousers from the crotch seam to the ankle.
- Hand circumference: measure around the hand using a tape measure or a piece of string and a ruler.

Fit: Castelli specialises in performance cycling apparel and many garments have a close-to-body fit. The manufacturer's general rule is to choose the larger size when your measurements fall between two sizes. Product-specific fit guidance always takes priority.
