Smartwool Intraknit All-Season Balaclava Nightfall Blue, One Size

What Our Gearhead(R) Experts Are Saying:"I've worn this balaclava through everything from windy ridgeline runs to cold morning rides and the mesh ventilation actually keeps me from overheating mid effort. The knit-in wind protection around my ears means I stop noticing the cold within the first few minutes."We push into a headwind that would normally send us straight back inside, and the Smartwool Intraknit All-Season Balaclava is what keeps us moving forward instead. Built for high intensity efforts in cold, unpredictable conditions, this balaclava works with the body instead of just insulating against the cold, letting heat escape where it needs to while blocking wind where it matters. Intraknit technology integrates insulation, articulation, and ventilation into a single seamless knit, so the fit moves naturally through big efforts without bunching or restricting. Targeted mesh zones vent heat during hard breathing, while a DWR finish around the ears and forehead sheds moisture when the weather turns wet.
