Abstract: A waterproof outer garment comprises one piece of material wrappable around the wearer between the knees and the back, with edges overlapping and securable to one another by quick locking and quick release fasteners. The edges are securable in varying amounts of overlap to adjust the garment to the size of the wearer, and suspenders prevent the garment slipping down on the wearer. In one embodiment, the entire garment is made from a material impervious to the ingress of water. In another embodiment, portions of the garment which are not subject to contact under pressure with snow and water are made of a lighter weight material which need not be waterproof. Garments according to the present invention which are made partly from non-waterproof material can be made lighter, more comfortable and perhaps more stylish than garments made entirely from waterproof material.
