SYSUM Women's Merino One Long Sleeve - Detail Front
SYSUM Women's Merino One Long Sleeve - Detail Back
  • Light cover for heavy work. Layer-able or packable.

    The lightest Merino running long sleeve on the market*. A 90 g/m² blend of merino wool and recycled polyester provides cover without weighing you down. Poly for strength and a fast dry, merino for natural cooling and odour control, each pulling its own weight. Wear it alone on hot days out (the breathability on this long sleeve is insane), or add it as your first layer when the weather turns.

    Naturally odour resistant. 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. Long sleeves add extra protection for your arms on exposed days, finished with a super minimal cuff. Merino also doesn't chafe, so somewhere out there you'll forget you're wearing it at all.

    Layer it over our Merino One Tee 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.
