Completely Waterproof. Tough. Durable. Adaptable. Dependable just as you’d expect from Kelly Kettle. Used as a camping tarp shelter, can withstand the heavy storm. Made from 190T Polyester Ripstop fabric with PU 3,000mm coating. Using Ripstop Technology - a technique of weaving where fibers are interwoven in a criss-cross shape (look for the checkered pattern in the material). This significantly improves the final layering and prevents the material from unraveling and a tear spreading. Seam is taped. Completely waterproof, even in the heaviest storms.
