How to Choose One-Piece Snowmobile Suits

Purpose
One of the important things to know before buying the right snowmobile suit is to choose one based on the purpose it is used for. This will help reduce the different possibilities that are available to pick from.
A rider that does not spend much time or is only snowmobiling as a recreational activity will not require a high-end suit that costs a lot. A simple suit with proper insulation and weatherproof characteristics will suffice.
An avid snowmobile rider that loves moving around when the temperatures are freezing cold outside will need better layers of clothing. So, a suit with proper insulation made of weatherproof material and more will be required based on the requirements.
Design
There are many clothing options that can be worn for winter and many of them look the same. But, only a few of them can keep you warm from freezing cold temperatures and high-speed winds when riding a snowmobile. So choosing the right design elements in the suit is very important. Some of the most important ones are the material, size, comfort, etc.
Material
The material used to make the snowmobile suit is one of the most important things to look for when buying a suit. It is important for a snowmobile suit to provide proper insulation from extreme weather conditions like freezing temperatures and high-speed winds. So, choose a material that prevents water and snow from entering the inner layers of clothing.
Cotton is a very bad material to wear in any layer of clothing, so avoid suits that have even a little bit of cotton in it. Acrylic, Gore-Tex, or any synthetic material that provides good insulation and waterproofing is a good pick.
Existing materials used for making the suits often do not provide both breathability and protection so, it is necessary to compromise between breathability and weather resistance and choose the best one. Based on the outer shell, the suits are divided into hard shells and soft shells.
Hard shells offer excellent wind and water resistance while providing little breathability. Softshells offer better breathability but the weather resistance is low. So, choose hard shells as perspiration will be low during snowmobiling.
Comfort
It is very important for the suit to feel comfortable while wearing. Comfort includes both how protected the suit will keep the person from the cold and how it feels on the skin. As the suit is the shell, it is important that there is enough flexibility for the person to move around wearing the suit for comfortable riding.
Price
The average cost of a good snowmobile suit is around $300. A cheap suit will not provide good protection from the cold temperatures and chilly winds. So, it is important not to switch to a lower quality product at a cheaper price.
As the suit will be a good investment that lasts for years, it is better to spend a little extra money to get a custom-made suit or a high-end suit for avid snowmobile riders. For those who take it up as a recreational activity, a ski suit can be used if it has good weather resistance to protect against the chilly winds.
Visibility
A good snowmobile suit will have reflective stickers and bright coloring to indicate that there is a person is present. This can be very important when riding in bad weather conditions with limited visibility and also during the night. So, pick a suit with bright colors and reflective stickers for better safety.
Varieties
Snowmobile suits come in different types like a single-piece suit that has zippers from the pant to the neck. This type offers good protection and prevents heat from escaping between the layers of the clothing. There are also two-piece suits with jackets and pants which are also effective in keeping the person warm.
Suits are specially designed for men, women, and youth differently and come in a variety of sizes for each. So, pick a suit based on gender and also age for better fit and comfort while riding.
Gender Appropriate
Men’s snowmobile suits are different than the ones designed for women. From width and length to the overall fit, men’s jackets are usually looser and longer, while women’s jacket comes with a slim fit.

Size and Fit
No matter you purchase branded Polaris snowmobile suits or the cheaper ones, the size of the product is critical. Before you order online, it is suggested to measure yourself and compare the results with the ones provided by the manufacturer’s sizing guide.
If you still have doubts about the size, you can go through a few online snowmobile suits reviews and read the customer’s opinion on the snowmobile suits.
Insulation and Ventilation

A few important features to look for in your snowmobile suits are the thickness of the insulation and ventilation technology used. In other words, you need to protect yourself dry and warm at the same time, no matter how the temperature is outside or how active you are.
Collar
Having a collar takes care of your neck and most of the suits have it lined with fleece and an adjuster to keep you warm all through.
Hood
Fixed or detachable, hoods are mandatory. Detachable hoods come in different closures including zipper, snap, or velcro closure.
Breathability
If you intend to engage in high-adrenaline activities, you will require highly breathable jackets. You will otherwise be at risk of developing hypothermia whenever the moisture and sweat get trapped within the jacket.
Internal Suspender
A few suits will have suspenders. Purchase suits that have an internal suspender as this holds the suit’s waist in place for it to fit well and comfortably.
Pockets
Just like snowmobiling pants, jackets, and snowmobile bibs, monosuits will also have pockets at different locations. Again, these pockets will be designed differently depending on the utility. For instance, a cell phone pocket will have a meshed lining to make it waterproof while the hand pockets will be lined with warm fabric.
Boot and Wrist gaiters
Gaiters protect your feet from snow, debris, and rainwater while insulating your feet and hands. They come with loops that pass under your snowmobiling boots to secure insulation. Your suit should help your warm snowmobile gloves to protect your hands from cold weather.
Construction
The best one-piece snowmobile suit is constructed with waterproof, breathable, and windproof fabric. It comes in two or three layers; an outer shell with lamination for some, an inner lining, and also insulation. Polyester, Gore-Tex, and Polyurethane are some common outer shell fabrics. When it comes to insulation, few have them separate while others have them built in the suit. Hence choose accordingly.
Seams
Double-Stitched seams indicate strength while a sealed seam signifies waterproof ability. A few suits will have only the critical seams sealed. Hence, purchase accordingly.
Zippers
Look for a two-way zipping feature. Aquaguard zippers are rated waterproof. Also, make sure to check they are durable and tough like the YKK zippers.
Final Words
Snowmobile suits protect yourself from all the weather elements, be breathable and still have some resistance to abrasion. You just need to ensure you find a good fit. These suits are good at providing a completely blocked-off environment so your body temperature is regulated effectively.
Snowmobiling suits come with different features which sometimes make it difficult to make the right choice. All you need to do is know your sport and the main features required. Go through the above-mentioned snowmobiling suits and you will definitely find your choice at the best price.
