The overalls are designed for those working in sewers, wading in water, providing effective protection against wind and rain. The upper part of the suit is made of two types of material which, when welded on both sides, effectively increases the strength of the seams. The S5-type safety wellingtons bonded to the upper part additionally protect the wearer's feet. Rib cuffs and a splash-proof zip at the back additionally prevent moisture from getting inside.
