For runs where the heat doesn't let up.

The M-Ossa runs on Coolcore Breeze, an open-knit recycled mesh with chemical-free thermoregulating threads that move heat and sweat off your head. One practical note on this colourway: the peak trim print placement varies slightly cap to cap, so the balance of grey and yellow you receive may look a little different from the product photo. Get in touch before ordering if you'd like more detail.

• Coolcore Breeze open-knit mesh: chemical-free thermoregulating threads move heat and sweat off your head instead of trapping them
• Pliable peak: folds flat for the bag, holds its shape when it's out
• Quick-adjust rear strap: sized to sit secure on a smaller head or a larger one, so fit isn't a guess before you buy
