SYSUM Women's Merino One Tee - Detail Front
SYSUM Women's Merino One Tee - Detail Back

  • Cool when it's hot, warm when it's not.

    The lightest Merino running tee on the market*. Made from a 90 g/m² merino blend, merging merino wool with recycled polyester. Poly for strength and a fast dry, merino for natural cooling and odour control, each doing what the other can't. Wear it alone through the warmer months (the breathability on this tee is insane), or as a base layer when the weather turns.

    Naturally resists odour. Built for days out, not just hours.

    The contoured fit isn't just for looks. A forward front shoulder seam sits away from pressure points under a vest pack, angled side seams stop the back-sag when you're moving, and with no elastane there's no bounce, keeping everything controlled from start to finish. Merino also doesn't chafe, so somewhere out there you'll forget you're wearing it at all.

    Layer it under our Merino One Long Sleeves or with any of our slightly heavier Merino Two range to dial in your temperature. Whatever the weather, whatever the distance.

    *if you can find a lighter one, let us know.
