Description

Face a cold and windy day head-on with our Thermal Merino Balaclava. This balaclava is made with 100% Merino wool to help keep your face warm, dry, and protected from the elements, without impacting your peripheral vision.

Ski and ride
Under a helmet.
Full coverage
Head, neck and face.
100% Merino
No blend.
Features
  • 100% Merino wool. No blend — the whole balaclava is wool, which is why it keeps insulating once your breath has dampened the face panel.
  • Double-layer construction. Two layers of Merino interlock over the head and neck, which is where the warmth comes from without the bulk of a heavy knit.
  • Cut for peripheral vision. The face opening is shaped to protect the face without narrowing what you can see out of the corner of your eye — the usual complaint about a balaclava under goggles.
  • Merino moisture management. Wool moves moisture as vapor, so the panel over your mouth and nose does not turn clammy on the skin track.
  • Odor resistance. Merino resists odor build-up, which matters more on a layer worn over the mouth day after day than almost anywhere else.
Size & Fit

One size, built for head circumferences of 21.5 to 23.5 inches (55 to 60 cm). The interlock knit stretches to pull on over the head, then sits close at the neck without gapping. The face opening is cut wide so it does not narrow peripheral vision under goggles.

Materials
  • 100% Merino wool.
  • Care: Machine wash cold on gentle cycle with like colors; do not bleach; tumble dry low or lay flat to dry; do not iron; do not dry clean.

Merino breathes well for its warmth, so moisture from breathing moves out rather than icing up against the face.

Double-layered, so not the thinnest option — but the interlock knit keeps it flat enough to wear under a helmet all day.

Best for

Is this right for you?

Cold and windy resort days

One piece covering head, neck and face means no gap opening at the collar on the chairlift, which is what a beanie and gaiter combination does.

Not for: On a mild spring day it is far more coverage than you want. Try the Thermal Merino Reversible Neck Gaiter instead

Ski touring and winter alpine starts

Wool over the face keeps insulating once your breath has dampened it, which is the difference that matters on a pre-dawn skin track.

Not for: Not a substitute for goggles — the face opening leaves the eyes exposed. Add the Unisex Merino Gloves

Sub-freezing commutes

Pull it up over the nose into the wind, push it down around the neck once you are inside.

Not for: Full-face coverage is more than most people want for an ordinary cold day rather than a genuinely cold one. Try the Thermal Merino Reversible Neck Gaiter

Questions, answered

Before you buy.

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
What size is it?

One size, built for head circumferences of 21.5 to 23.5 inches (55 to 60 cm). The interlock knit stretches to pull on over the head.

Will it fit under a helmet?

Yes. The interlock knit sits flat enough to wear under a ski or climbing helmet all day, and the face opening is cut so a goggle frame sits over it rather than fighting it.

Does it block peripheral vision?

That is exactly what the cut is designed to avoid. Smartwool shapes the opening to cover the face without narrowing what you can see out of the corner of your eye.

Will the mouth panel ice up?

Less than a synthetic one. Merino moves moisture as vapor and keeps insulating when damp, which is precisely the problem a face panel has. On a hard, cold day it will still get damp — that is physics, not a fault.

How do I wash it?

Machine wash cold on a gentle cycle with like colors, then tumble dry low or lay flat. Do not use a hot dryer — heat is what felts and shrinks wool.
