The FSTCap SC Classic Cside builds on the success of Ciele’s original 2015 FSTCap with thoughtful upgrades to meet the demands of today’s runners. This refined version keeps the signature smaller fit and low profile that set it apart from bulkier caps, now enhanced with Ciele’s latest COOLmatic | PLUS™ fabric for improved breathability, cooling and odour control during intense efforts.
About FSTCap SC Comp Ninety SL Canvas
With UPF +40 protection on the brim and front panel, it offers reliable coverage on sunny days, while its pliable SOFTcurved brim ensures packability for on-the-go use. The quick-drying, lightweight construction combines performance-driven COOLmatic fibres and Repreve recycled fabric, helping you stay comfortable while reducing environmental impact.
Reflective details add visibility during early morning or evening sessions, and the fast-fit, low-crown shape provides a snug, aerodynamic feel without sacrificing comfort. Weighing just 50 grams, this cap strikes the perfect balance between minimalist design and technical performance.
Like all Ciele caps, it’s backed by the brand’s Million Miles Guarantee and made for runners who expect more from their gear, on race day and every day.
How does it work
The FSTCap SC Classic Cside uses COOLmatic | PLUS™ fabric to regulate temperature by accelerating moisture evaporation and increasing airflow across the head. The addition of odour-control properties ensures that even on your longest or hottest runs, the cap stays fresh. The SOFTcurved brim adds comfort and structure, while also folding down for easy packing. Repreve recycled fibres bring sustainability into the mix, making it a smart choice for environmentally conscious athletes.
This streamlined cap fits securely without excess bulk, providing sun protection and a cooling effect, all while maintaining a barely-there feel.
