Women's S-HEARTWOOD Running Singlet
Recycled mesh with breathable, sweat-wicking stretch - More Info

Named after the terrain, not a marketing team.

The S-Heartwood is Fractel's Coolcore Breeze singlet in yellow, a recycled mesh with chemical-free thermoregulating threads for sweat-wicking breathability when the pace picks up. Four-way stretch is tailored for a natural stride, cutting the risk of chafe over distance, finished in a limited edition Sierra Nevada print.

  • Coolcore Breeze recycled mesh: chemical-free thermoregulating threads wick sweat and manage heat as the pace lifts
  • Four-way stretch, tailored for a natural stride: cuts the risk of chafe over distance
  • Reflective details: added visibility at dawn, dusk or low light
