Sioen's 4500 Rotterdam Classic Rain Trousers are durable, comfortable and 100% waterproof - ideal for working in wet weather conditions. Thanks to Sioen's patented Flexothane material, the Rotterdam trousers will protect you from the wind and rain for years.
These simple rain trousers have an elasticated waist, so they are easy to put on and comfortable to wear. The legs can be narrowed at the ends using press studs, so they can be securely fitted over safety boots or wellingtons. High frequency welded seams give the garment additional durability while also creating an effective barrier against water. It is strong, supple, lightweight, noiseless and easy to care for. They are also machine washable up to 40°C.
