What sets the PYN apart is the removable neck protection, a snap-on, snap-off design that offers vital shade without added bulk. It’s a game-changer for ultra races or desert-like conditions where every degree of cooling counts. Reflective detailing ensures visibility for early starts or late finishes, while the pliable SOFTflat brim makes it easy to stuff into a vest or pocket when the clouds roll in.

Like all Ciele caps, the GOCapPYN is built to last, backed by their Million Miles Guarantee. It’s fully machine washable and constructed from recycled performance fibres, blending environmental responsibility with premium performance. The 5-panel construction provides a secure, comfortable fit that moves with you.

Whether you’re chasing a PB or just enjoying the summer miles, the GOCapPYN Comp One Hundred is your go-to for sun-smart, high-performance running gear.

The GOCapPYN Comp One Hundred is engineered for optimal airflow and cooling using COOLmatic | PLUS MIKRAmesh™, which draws sweat away from the skin and promotes rapid evaporation. The FLEXweave construction ensures a stretchy, contoured fit while remaining breathable even in extreme heat. The snap-on neck protector adds an extra layer of sun defence and can be removed in seconds when conditions ease.

UPF +40 protection built into the fabric shields your head and neck from harmful rays, and the SOFTflat brim offers structure without rigidity, meaning it can be packed down without losing shape. Reflective accents round out its performance features, making it ready for any time of day.
