Built to perform
Built for extreme winter riding, the 509 Allied 2.0 Insulated Monosuit in Stealth delivers full-body protection, durability, and advanced cold-weather performance for snowmobile, snow machine, and backcountry riders. Featuring the updated 5FLEX stretch shell, this snowmobile monosuit provides 10K/10K waterproof-breathable protection, excellent mobility, and dependable comfort on long or aggressive rides.
Strategic zonal Synloft insulation delivers up to 400g of warmth in wind-exposed areas, paired with Aurora microfleece waffle lining to manage moisture and maintain heat without unnecessary bulk. Fully seam-taped construction, PFAS-free DWR, and YKK Aquaguard zippers ensure riders stay dry in heavy snow, slush, and high-speed conditions.
For added safety and performance, the suit integrates the new F.I.T. protection system—Float, Impact, and Thermal protection—along with expanded knee space for mobility and comfort. Venting, 3/4 leg zips, a removable hood, and secure closures round out this high-performance snowmobile / snow sled / off-trail insulated monosuit.
