The rule here is that you can always remove layers if you get too warm. Your best choice is long underwear that is lightweight and doesn’t restrict your movement. Generally speaking, fabrics which wick moisture away from your body are ideal. These are often synthetic blends. Avoid wearing cotton, which simply absorbs moisture and can make you feel even colder.
Buy suits with outside shells that are windproof and waterproof. There are many makes on the market to suit your specific budget. Avoid anything cotton, which can become saturated with snow.
Buy an approved helmet, which is your most crucial piece of equipment. Snowmobile helmets are mandatory in Canada. There are many models on the market, and your choice will depend on your budget. Helmets can greatly reduce your chances of head injuries. Helmet visors protect the face and eyes from cold as you ride.
For extra protection from frostbite, some snowmobilers feel facemasks are essential. This is especially true if your helmet is not a full-faced model. The most common facemasks are made of thin, synthetic fabrics. These are superior to wool or knit-stocking facemasks.
Sunglasses or goggles
You need to protect your eyes from dangers such as flying debris, sunlight, water and cold. Some snowmobilers prefer goggles to sunglasses, depending on their helmet model. For late afternoon driving, you can try amber or yellow-coloured lenses.
Gloves and mittens
Whether you choose gloves or mittens is mostly a matter of personal preference. Whatever you do, make sure that you can manipulate the snowmobile controls easily. Like any outdoor clothing, your gloves or mittens should repel water and wind. The best brands are made from synthetic fabrics which keep moisture away from the skin. Generally speaking, wool mittens are effective in warmer weather, since you can always add or remove the liners.
First and foremost, avoid wearing cotton socks; they just absorb moisture and can actually make your feet feel even colder. The blends that provide good insulation are synthetic and thin or thicker wool.
Ideally, your boots should have a rubber, waterproof bottom and good traction to avoid slipping. The upper part of your boot should have a nylon or synthetic shell and a removable liner made of wool, fleece or synthetic materials that keep perspiration away from the foot. Buy boots that give your toes room for movement and don’t cut off your circulation.
