Sioen 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.

The 4500 Rotterdam trousers are made with Sioen’s Flexothane Classic material (100% polyamide knitting with polyurethane coating; ± 180 g/m²).  Flexothane has an unrivalled elasticity and tear strength in the foul weather protective clothing market.  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.  It is also machine washable up to 40°C.

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.  Ideal for outdoor and offshore work.  Recommended for use with the Sioen 4820 Dortmund Rain Jacket.
