Snowmobiling enthusiasts understand the importance of proper gear for comfort, protection, and performance on the trails. When it comes to snowmobiling apparel, mono suits have gained popularity as a convenient and practical alternative to the traditional jacket and bib combination. 509, a leading brand in the industry, offers a range of mono suits with distinct features and suitability for various snowmobiling adventures. Let's explore the differences between 509's mono suits and understand why they matter. 

Firstly, what exactly is a mono suit? A mono suit is a one-piece snowmobile suit that combines a jacket and pants into a single garment. This design provides complete coverage and eliminates the need for separate jacket and bibs. Snowmobilers benefit from wearing a mono suit in several ways compared to a traditional jacket and bib combination. 

Allied Mono Suits

509's Allied Mono Suits are available in both shell and insulated styles. These suits utilize 5Tech and Cordura materials, providing excellent durability and weather protection. Both the insulated and shell styles are recommended for backcountry and crossover snowmobiling. The insulated style is particularly suitable for crossover terrain as it offers less airflow, providing added warmth in colder conditions. On the other hand, the shell style is recommended for mountainous environments, offering a mid-flow design that balances airflow and protection. The Allied insulated style incorporates 3M Thinsulate Insulation for enhanced warmth, while the shell style does not feature insulation. The newly-updated 509 Allied Mono Suit Shell is designed to excel in harsh weather conditions. With fully seam-taped, waterproof/breathable fabric and burly, triple-stitched Cordura 300D polyester construction, it offers exceptional weather protection. The updated crotch gusset improves fit and mobility, while the new zipper fly allows for convenient pit stops.
