M-HEARTWOOD Running Cap

M-Series Premium

£40.00
M-HEARTWOOD Running Cap
Recycled mesh with breathable, sweat-wicking stretch - More Info

For runs where the heat is the whole problem, not just part of it.

The M-Heartwood, in yellow, runs on Coolcore Breeze, an open-knit recycled mesh with chemical-free thermoregulating threads that move heat and sweat off your head. Finished in a limited edition print.

  • 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

Explore the whole M-Series lineup, part of our wider running caps collection.
