Thermal Merino Reversible Headband

The Smartwool Thermal Merino Reversible Headband keeps wind in check without adding bulk. Made from 100% Merino wool in a double-layer interlock knit, it delivers natural warmth, moisture management, and odour resistance in a slim profile that disappears under helmets and hoods. The reversible design gives you two looks in one, while the cleanly finished seams create a smooth, snag-free fit that stays comfortable during runs, hikes, commutes, or shoulder-season training sessions. Lightweight, breathable, and reliably warm — it’s a small piece of gear that makes a big difference when the wind picks up.
