Search results show two main categories: fashion waist belts (thin PU or bonded/faux leather styles and wide elastic styles) and water-ski buoyancy waist floats designed for swimming, boating, and stand-up paddle (SUP) use.
Fashion belts: hand wash, avoid contact with liquids or oils, and wipe with a dry cloth. Water-ski buoyancy belts: vinyl-coated and described as easy to clean—wipe dry after use.
Listed materials include PU (polyurethane), bonded/faux leather, vinyl-coated closed-cell foam (for buoyancy), metal components, and—on one listing—elastic.
One listing offers eight colors: gray green, red, camel, black, white, coffee, brown, and dark brown. Another lists four colors: black, brown, beige, and red.
