The small but mighty balaclava is the pea under the mattress of the modern snow world. It might be little. You might think it won’t make a difference which one you get. You might think you won’t notice the difference, anyway. But half a day in, skiing down the slopes and burying yourself in face shot after white room after snow blower to the face? We're all princesses at heart, and we notice the difference.
Choosing the right balaclava is the difference between a good day and a cold, miserable one. No one wants a balaclava or neckwarmer that ends up soaked through from your own breath, frozen stiff, cold, clammy, and scratchy against your face the whole ride down. And lucky for you, that’s a synthetic problem, not a Merino one. Here’s how to choose the right Merino wool balaclava for your day.

What is a balaclava, and do you actually need one?
A balaclava is full head-and-neck coverage in one piece. Think a classic neckwarmer or neck tube that wraps around your neck, but also pulls over your forehead at the top, and pulls up over your nose and mouth. Big bank robber vibes. No gaps at your collar, no sliding down at the worst possible moment. And if you’re skiing in the cold, riding with a bit of wind, or just don’t like cold air in your face or down your neck while you ride: yes, you need one.
Some riders reach for one on any day with wind, altitude or speed in the mix. Others prefer a neck warmer in warmer weather, then layer up when it gets cold. There’s no wrong answer, it’s about how you like to protect your face, and what the conditions call for.
Merino vs synthetic balaclavas: why it matters next to your face
When you're breathing hard or battling the elements, it doesn't take long for moisture to build up when you're wearing a balaclava over your nose and mouth. The problem with synthetic balaclavas is that they trap that moisture around your face, often soaking it up and freezing into a solid, cold mask that feels like sandpaper against the sensitive skin on your face. It also gets cold, fast.
The benefit of Merino wool balaclavas is that they're constantly moving that moisture out instead of trapping it. That's because Merino is scientifcally proven to buffer moisture 96% better than polyester. It pulls moisture away from your skin, absorbs up to 30–35% of its weight in moisture, and releases it before you feel wet. Merino wool balaclavas are soft, warm, breathable, and keep you warm even when wet, making them the logical choice when you're riding the mountain.

How to choose your balaclava weight, coverage and fit
Not all Merino wool balaclavas are built for the same day. Before you buy, think about three things:
- Weight. Lighter Merino (around 190gsm) is your everyday, most-conditions option, warm enough for cold laps without overheating on the uphill. Heavier constructions are built for winter days when warmth is king.
- Coverage. Coverage really comes down to preference, and how you like to protect your face. Full face coverage is ideal for combatting the cold or high wind exposure. Some styles pull up over your nose and mouth for full coverage, then hinge down to sit around your neck like a neckwarmer once you don’t need it. That’s what a lot of riders prefer, and becomes even more important if your day involves any climbing, touring or variable conditions.
- Fit. A balaclava that’s too loose lets cold air in around the edges and defeats the purpose. Too tight and it’s uncomfortable under a helmet for hours or might feel restrictive when you breathe. Look for a snug, three-panel construction that moves with your face rather than bunching up.

How to wear a balaclava under a helmet
A well-designed Merino wool balaclava should sit close and flat to your head, without bulky seams or fabric buildup that pushes your helmet off its correct fit. Start by pulling it on first, before your goggles, glasses, or anything else. Smooth out any bunching at the crown and make sure it’s sitting snug. Then put on your helmet, followed by your goggles, and make sure everything is clipped up and secure. Check our size guide if you’re not sure on sizing. And if you’re moving between conditions, look for a style that can be worn a couple of different ways: up over the nose and mouth in a whiteout, or dropped to the neck when you warm up on the way back to the lift.
How to wash your Merino balaclava
Merino is pretty low maintenance to wash and care for, and doing it right means your Merino will last you a whole lot longer. We recommend a cold-warm machine wash (<30°C), mild detergent, no fabric softener, and line drying in the shade. Check out our full Merino care guide for more information, and always follow the washing instructions on your garment. It also dries faster than most synthetics, which matters if you’re washing between big days.
