spring 026 headwear. same standard. new colours.

last year we re-invented our headwear structure to make it easier for everyone to find their perfect fit. three core crown silhouettes. available in multiple sizes (S/M 56.5cm, M/L 58cm, L/XL 60cm).

this spring, we added new shades to the lineup

all available in new colors for the warm weather ahead, with all of the technical run-driven features you'd expect from a cap built to run a million miles with you.

the GOCap
the original. the archetype. the industry standard soft brim run cap. race proven from boston to charlevoix, and your local 5k as well. seasonal availability of both pre-curved and flat brims.

the FSTCap
the lowest crown in the collection, meaning a more fitted look.

the TRL.Cap

a re-engineered fit and a higher crown for more air circulation and, as a result, quicker cooling. the TRL offers the highest crown in our headwear collection.

we've never taken headwear for granted. visit our fit finder to learn more.

this spring, we added new shades join the lineup — harbor, mulberry/bocasana, canva and kombu. our commitment is to build the best technical headwear in the world, and ensure that every runner finds the colour, branding, and style they want.
