Best Snowmobile Suit

Whether I’m riding through extreme winter cold or racing my friends, I like to have a snowmobile suit as an available option for the added warmth and protection it provides. I’ve tried several different suits over the years and have a few favorite options to recommend. 

The 509 Allied Monosuit is one of my go-to choices and the best choice for a snowmobile suit. 

The Allied will give you extra warmth and protection against moisture so you can blast through the snow all winter long. Plus, it’s exceptionally comfortable and looks cool as well.

There are a few other suits well-worth trying out that I’ll highlight in this post. You don’t need a suit for snowmobiling, but I think it’s nice to have one just in case. 

Time to zip up and get after it!

Quick Summary

Top Choices for Best Snowmobile Suit

Call it whatever you want – a snowsuit, coveralls, or a onesie; these are some of the warmest and most comfortable winter weather suits around. They can be more expensive than regular pants and a jacket, but well worth it when the temperature plummets. 

1. 509 Allied Monosuit

  • Best for: Overall
  • Key features: Excellent warmth, supreme comfort, full seam taped, DWR C8 coating, good ventilation, internal suspenders
  • Materials: 5TECH, Cordura HP 300d Polyester
  • Waterproofing: 10K Membrane
  • Fit: Regular

The 509 Allied Monosuit is my top recommended choice for a snowmobile suit. It offers high-end performance across the board and should meet the needs of just about any rider. 

It’s made of a unique 5TECH material that 509 uses in many of its winter weather items to provide a serious barrier against the wind and snow. This works with Cordura HP 300D Polyester to provide excellent waterproofing. 

If that wasn’t enough, the entire suit is coated with a DWR C8 treatment for long-lasting water repellent protection. Simply stated, the Allied is going to keep you dry for years. 

It will provide you with excellent warmth, and you won’t need to worry about wind creeping in thanks to fully-taped seams. A ventilation system with zips and flaps in the pits, side, and thighs will let in airflow when you need it. 

The Allied also comes with Asymmetric cuffs and wrist gators to keep your sleeves in place and internal suspenders for another layer of lasting comfort. 

It has a regular fit, which can be a little small compared to other more baggy snowsuits. You might want to order a size up with that in mind. 

2. Tobe Novo V3

  • Best for: Backcountry
  • Key features: Rugged design, Armortex Kevlar reinforced areas, 100% windproof and waterproof, leg gaiters
  • Materials: Sympatex, Cordura
  • Waterproofing: 45K
  • Fit: Comfort

If you are looking for a suit that will take a beating and live up to the demands of the backcountry, the Tobe Novo V3 goes above and beyond. 

This is a rugged and extremely durable option built with nearly indestructible Armortex Kevlar reinforced areas on top of a Cordura nylon and Sympatex shell. You can put this suit through the wringer, and it will still look brand new. 

It also comes in an insulated or non-insulated version to match the conditions and the weather you ride in most often. The Sympatex layer gives it an unreal 45K waterproof rating. 

Additional features include full-leg zips, a removable hood, adequate ventilation, and it’s incredibly comfortable to boot. This is a high-end option in all of its glory. 

The bad news is, this is by far the most expensive snowmobile suit I’ve ever seen. It will probably last a lifetime, but expect some sticker shock if you’re interested. 

3. Carhartt Arctic Quilt Lined Yukon Coverall

  • Best for: Budget Pick
  • Key features: Extremely durable, heavyweight design, warm, zippered pockets, double-layer knees
  • Materials: 100% Cordura Nylon
  • Waterproofing: Water-repellant 
  • Fit: Baggy

Carhartt Coveralls are the utility choice and have been a go-to option for many different winter activities for years. The Arctic Quilt Lined Yukon makes for a solid snowmobile suit that is also more affordable than the other options. 

You can expect plenty of comfort out of this one, and it has a baggy fit that will allow you to move around with ease on and off your sled. 

Double kneed construction provides added durability, and a heavyweight 1000 denier Cordura nylon shell will keep you warm and protected. 

It also features two-way zippers for easy use and storm flaps for added protection against the elements. 

This is a warm option, but it isn’t the most waterproof. There is no technical waterproofing, and if you ride in wet conditions, it will start to get soggy. It also doesn’t come with a hood. 

If you want a cheaper set of coveralls for riding or are a fan of Carhartt, this is still a recommended option. 

What to Look for in a Snowmobile Suit

The following factors are good to keep in mind when you are shopping for a snowmobile suit. 

Insulation/Waterproofing

One of the main advantages of a snowmobile suit over the standard winter jacket and pants combo is that a suit limits airflow and keeps all of your body heat contained. This boosts its insulating properties by design, and suits are a warmer option. 

A key to staying warm and comfortable while you ride is staying dry. You need to make sure the snowmobile suit you choose is fully waterproof and will remain so even when the weather is terrible. 

GORE-TEX and other treated synthetic fabrics offer a lot of waterproofing and will remain effective for season after season of use. 

Ventilation

Snowmobile suits are a warmer item, which is excellent for cold weather. But if you wear one of these on a milder winter day, you can easily get overheated. That’s why I always recommended choosing an option with adequate ventilation. 

Zippered pits and legs will allow heat to escape and keep you cooled down. Zippered vents are nice because they will enable you to adjust how much airflow comes in or goes out for customized comfort. 

Additional Features

You might have certain features that you are looking for in a snowmobile suit. Each model is a little different so always be sure to read the description to make sure it comes with everything you want and need. 

I like a suit with a hood, boot gaiters, plenty of pockets, and reinforced material in heavy wear areas such as the cuffs and seat. These are standard features on every option listed here but might not be if you look elsewhere. 

My Verdict

The best snowmobile suit, and my personal favorite, is the 509 Allied Monosuit. This is a super comfortable option that will give you excellent warmth and cold-weather protection while coming packed with other features that can be useful on the trail. 

A snowmobile isn’t an essential item, but I certainly think it can provide you with better warmth and comfort for anyone who rides often and for extended periods. Getting one can come in handy, even if you only use it a few times every year.
