King of merino balaclavas.

Tried a few different setups, since moving to a snowboard helmet with no liner. And this is is the way! Warm enough, great fit, can manage sweat/snow, and doesn't look crazy. If you're wearing a mountaineering style snow helmet, this is the bit of kit that rounds out the functionality.

Just what I needed for winter hang gliding flights!

This thermal merino balaclava is great! I wear it under a helmet, so I needed something thin, but warm. The wool is stretchy and comfortable, and best of all, it keeps me warm during my hour+ hang gliding flights where it can get quite cold!

Very warm and breathable. Good for skiing because it fits easily under a helmet. High quality all around.

Keep 1 in your back pocket

I honestly love these. Can't get enough of them. My skin doesn't do well with synthetic materials especially around my face. Thanks SMARTWOOL.

Perfect cold weather item here in the PNW

Warm, light weight, comfortable fit even after machine washing, dries quickly, nice construction, functional as a neck gaiter also. I'm a contented customer and ongoing "hot head." A recommended purchase.

Exactly what I was looking for

Love this! I returned a different Smartwool balaclava because it wouldn't stay up on my nose. This is EXACTLY what I was looking for. Smartwool was kind enough to give me a credit for the other balaclava so this was no more out of pocket money. Very happy with this product and their customer service.

Nice and form fitting!

I use this under a snowmobile helmet, and it is great because it is far more form fitting than others I've tried (which bunch up and/or slide down over my eyes).

I have several for winter.

Great item. Valuable to me. very. Not too heavy or bulky. Helps moisture management during exertion. I hate cold from drying sweat, wind or cold; this item really solves cold. When really cold, I wear under a hat . useful when windy or if you are camping out; covers head and neck.When cycling, critical item for wearing under my too-breezy helmet. Small. easily folded into a pocket. Easily laundered. I hang mine to dry. dries fast too. Keeps carotid arteries covered (those two on your throat) You can also wear glasses, as garment does not interfere. Glad to see lighter color. Black color harsh against face. Covers cold sores on lip too. Keeps solar radiation off face. Only con is this item really makes short, female hair look weird or flat. But, who really cares? A warm head and neck to me more important than cosmetics.

Bought to replace a Nike balaclava

I bought this to replace a Nike balaclava. There's not enough space to say how much I enjoy this over the Nike balaclava, but his balaclava fits a lot better.

yep I like it a lot and bought a spare

The "THERMAL MERINO BALACLAVA", works great for cold weather and winter bike riding along with the "ACTIVE FLEECE WIND HEADBAND", and...THERMAL MERINO REVERSIBLE CUFFED BEANIE" or "Creek Run Beanie" .I use all three when riding, and when it gets really cold and windy I put the "Seirus NeoFleece Combo Scarf" on too :-) That usually happens when the wind is over 12-15 mph and chill temp is around zero (with the temp/wind taken into account). I ride 10 miles almost daily in the winter so I've had lots of practice finding what works..Yes..I have studded snow tires on my bike. I also have on clear safety glasses or my "POC" ski goggles for the wind cold/wind too. It's almost always windy in the winter when I ride in Northern Idaho :-)

I would buy this again and again and I do!

I cannot ski or walk the dog without this under my helmet or hat because I live at 10,000 ft. It's the most perfect product smartwool ever mad and thrilled it came in baby blue this year!

Okay Balaclava - has some design issues

I use this on colder days and fits fine but very annoying having to adjust every time due to the bottom mouth portion being slack and not secure. Big nuisance

Very warm and odor free.

Great balaclava for cold ski days. Just wish the face hole didn't stretch out so quickly. It was perfect when I first put it on, but after one use the hole was stretched out and less form-fitting.

Nice and lightweight

Nice and lightweight. My 12 years old son can carry it in his jacket pocket without the bulk like other brands. He also slept in it during a 25 degrees scout camping trip. It kept him warm and comfy at night.

FEATURED REVIEWS

Lightweight, but warm. Fits well

By northern o.

This is a standard part of my winter fishing gear. It allows me to either wear a baseball style cap over it to help keep the sun out of my eyes, or on those very cold days a knit hat on top. It fits well and I like it enough to have bought 3 of them. 1 for work, 1 for home, and one in case I loose one.

Excellent head-and-neck baselayer!

By STP 1.

Love this balaclava! I bought it a couple years ago, and don't know how I lived without it. I live in USDA zone 4, where it gets down to -25F in winter. Mainly use it for trail-hiking and snowblowing on cold winter days when a single hat and scarf layer isn't warm enough. I wear it as a base-layer, underneath a wool hat and neck gaiter. This balaclava is high quality, in design and construction. Generous in size, even fits my husband's big head, and the neck length is excellent. Good quality...

For cold and windy days, don't forget to cover the bits of your face left exposed by a hat and gaiter. Made from Merino 250 Next-to-Skin fabric, the Balaclava keeps you dry and warm while still enabling good peripheral vision.
