In their quest to produce that perfect cap, they not only succeeded, they redefined the category. And it wasn't just their bright, bold colourways and impeccably cool styling that gained them their cult-like following, a commitment to performance and comfort is clear in everything they produce. Technical fabrics are ultra-lightweight and wick sweat quickly, whilst liberal reflective detailing keeps runners safe in low light. UPF +40 sun protection prevents burns whilst machine washable materials make cleaning a cinch. Many models utilise Repreve fabrics (100% recycled polyester), so their green credentials are top notch too. Their Million Miles guarantee rounds off an impressively comprehensive offering from a brand whose spot on The List was never in doubt.
