Abstract: A cover for protecting snow ski bindings from the elements is described. The protective cover encases two (2) bindings simultaneously with two (2) layers of flexible material, the inner layer being waterproof. Fastener straps are attached to the outer layer to hold the cover in place. This waterproof encasement protects the bindings when the skis are being transported or are placed in storage. The ski poles are attached to the outside cover by suitable fastener straps.An additional strap, attached to the protective cover, forms a sling to permit the skier to conveniently transport the skis to and from the slopes. When the protective cover is not in use, it is folded and stored in a pouch. The pouch when connected to the additional strap may be worn around the waist by the skier until the protective cover is again needed. A cloth red cross is also stored in the pouch which may be attached to the cover by suitable fastening means.
