509 Allied Mono Suit Shell – Waterproof Snowmobile One-Piece Riding Suit

509 Allied Mono Suit Shell

Engineered for the deepest powder days and biggest snowmobile missions, the 509 Allied Mono Suit Shell combines full-body coverage with the freedom to ride hard. Constructed from 5TECH waterproof breathable fabric with a 10k/10k membrane, fully taped seams, and Cordura HP 300D polyester reinforcements, this one-piece design keeps out snow, drafts, and moisture.

The Allied is packed with rider-driven details like internal suspenders to keep it in place, asymmetric cuffs with wrist gaiters, and a helmet-compatible hood. For ventilation, it includes three sets of zippered vents (inseam, outseam, and underarm) so you can dump heat on the go. Multiple waterproof pockets—internal, chest, thigh, and hand—offer secure storage, while burly Cordura instep and lower-leg reinforcements protect against sharp sled running boards.

Whether you’re mountain riding, boondocking, or hucking drops, the Allied Mono Suit is a must-have for riders who demand durability, mobility, and complete weather protection.
