M-ULLDO Cap

M-Series Premium

£38.00

The FRACTEL M-Series Cap is built for hot-weather performance on the run. Featuring our most advanced cooling fabric to date, Coolcore® Breeze™, this cap delivers lightweight airflow and ultra sweat-wicking performance. Made from a recycled open-knit mesh with chemical-free thermoregulating threads, it's built to keep you cool when you need it most.

A pliable peak allows for easy packability, while the quick-adjust spandex strap at the rear provides a secure, personalised fit.

Finished with a new woven logo design for added durability and texture, this cap pairs technical function with bold expression, built for the road, track, and trails ahead.

Looking for more performance-focused designs? Explore our full range of Bucket Hats, Legionnaire Hats, and Visors to find the perfect match for your next run.
