Abstract: A snowmobile seat having a ventilation system for allowing moisture that enters the cushion portion of the seat to be wicked away through a base section that is disposed between the tunnel of the snowmobile and the cushion. The base section provides ventilation spaces between the base section and tunnel and has ventilation holes there through that allow the moisture to be drawn away from the cushion. Grooves formed in the underside of the cushion and channels formed in the top side of the base section also help promote this process.
