The Sea to Summit Collapsible Kitchen Sink is an all-purpose folding sink for hauling water, meal prep, dishwashing, and personal hygiene when backpacking, camping, bike packing, and adventuring outdoors. Made from 70D waterproof nylon with fully taped seams, it’s safe to use with mild soaps and detergents (no bleach) and hot water up to 140 degrees Fahrenheit. Free-standing when filled, its wide base and stainless steel stiffening ring prevents the sink from collapsing when full. The Sea to Summit Collapsible Kitchen Sink features wide webbing handles for easy carry, and includes a zippered storage pouch with a drain hole. Practice Leave No Trace principles by using at least 300 feet from water sources. Available in three sizes: 5-liter (1.3-gallon) sink measures 11 x 9 x 4 inches, packs to 4.5 x 1.75 inches, and weighs 3.5 ounces; 10-liter (2.6-gallon) sink measures 15 x 11 x 6 inches, packs to 5.5 x 1.75 inches, and weighs 4.7 ounces; 20-liter (5.2-gallon) sink measures 18 x 14 x 7 inches, packs to 6.25 x 1.75 inches, and weighs 6.6 ounces.
