We originally designed this waist belt treat bag for a customer that does canine hydrotherapy and then adapted it for a customer who does PWD water sports. The belt is made of 1-1/2” (38mm) wide, heavy-duty polypropylene webbing and has an adjustable, side-release, non-corrosive acetal nylon buckle. The 7" wide by 4" deep (18cm by 10cm) treat bag slides on the belt and is made of heavy-duty, durable PVC-coated mesh with a 100% polyester scrim with a Velcro pull-open top for quick access to treats. Unlike nylon webbing, polypropylene webbing floats, does not absorb water and has a higher resistance to oil, grease, acids and other chemicals, and won’t mildew. Machine washable, cold water. Air dry. Two sizes: 1-adjusts 24" to 36"/61cm to 91cm; 2-adjusts 36" to 48"/91cm to 122cm.
