Abstract: A recreational vehicle such as a snowmobile, personal watercraft, all-terrain vehicle, motorcycle, or boat has a straddle-type seat that includes a flexible sheet of material pulled tightly over a gap formed in a seat frame. In certain embodiments, a tightening mechanism ensures that the flexible sheet of material is pulled tightly over the gap. The flexible sheet of material forms a hammock-like straddle-type seat. The flexible sheet of material is a mesh material that allows water, snow, dust, and other debris to fall through the mesh to avoid debris buildup on the seat. Because water falls through the mesh material and both the top and bottom sides of the mesh material are exposed to the ambient air, the seat dries quickly.

Abstract: A snowmobile is described having a frame, at least one steerable ski disposed at a forward end of the frame, and an endless drive track disposed beneath a rearward end of the frame to propel the frame. A seat is mounted on the frame, which may accommodate at least one person. A fairing is disposed behind the seat, and a storage compartment is defined interiorly to the fairing. Variations are also described.

Abstract: A breathing mask is provided for a helmet which reduces the formation of water on the lens of the eyeglasses of the wearer or on the shield of the helmet. The helmet comprises a head portion, a shield portion, and a breathing mask. The shield portion comprises a jaw shield and an eye shield. The breathing mask is hermetically adapted to the face of the wearer to evacuate the wearer's breath outside the helmet through breathing channels. The jaw shield can be pivotally opened or closed and is locked to the head portion in the closed position. The eye shield is pivotally connected to the head portion and includes a see-through shield and a tinted shield. The tinted shield can be lowered inside the helmet to protect the wearer from sun rays and reflexions.
