Official Mont-Tremblant gives you more information on snowmobile in Tremblant including what to wear for snowmobile.

Are you new to the sport and need a guide for essential snowmobiling gear to bring along on your first snowmobile ride? Official Mont Tremblant is here to help.  You need proper apparel and gear to ensure your snowmobile outing is safe and enjoyable. Make sure you dress in layers to be prepared for changing weather conditions which can vary greatly from when you start your trip to when you return. Wind chill factors experienced along with your moving snowmobile must also be managed to prevent potential effects from frostbite and hypothermia. Most importantly, always avoid cotton materials in all your clothing layers since cotton can get wet and freeze and does not wick moisture away from your body, drastically reducing your comfort and safety.

We have a complete clothing checklist for you because deciding what to wear snowmobiling is the most important factor to ensure a comfortable ride. 

• Base Layer: Wear synthetic thermals that are tight fitting for your top and bottom pieces. 
• Mid Layer: Fleece is a comfortable midlayer to wear.  We recommend fleece pajama bottoms paired with a hoodie.
• Outer Layer: Snow pants and a PUFF jacket (down or synthetic) are the warmest
• Socks & Boots:  Your footwear should be waterproof boots or shoes designed to repel water. You can find snow boots or shoes with wool lining inserts if you need that extra bit of insulation to keep your toes nice and warm.
• Gloves & Mittens:   We recommend bringing both, as well as, hand warmers.
• Head Gear:  A nice warm cap with a tight weave works well.  We recommend a fleece hat.
• Goggles: Goggles with multiple lenses for different weather conditions, and replacements. You should protect your eyes against any snow and ice that can kick up.
• Balaclava or face mask
