The Neverkink Heavy Duty garden hose is manufactured with NTS Reflex Mesh patented technology. This technology prevents the hose from kinking, twisting and tangling. The MicroShield antimicrobial protection guards the hose against mold and mildew that can cause hose deterioration. The protective collar prevents kinking at the faucet. The solid brass octagon coupling provides a wrench-tight, no leak connection at the faucet. Made in the USA.
