Quechua Men's Nh500 Waterproof Rain Jacket in Slate Blue, Size Small

The waterproofness of a fabric, provided by a coating or membrane, is measured in Schmerber or mm H20 (pressure exerted by a column of water). The higher this number, the more waterproof the fabric. This jacket is designed with a waterproof coating (JIS 1092 standard): this component resists 5, 000 mm H20 (Schmerbers) before washing (equivalent to the pressure exerted by a 5 metre column of water). | Quechua Men's Nh500 Waterproof Rain Jacket in Slate Blue, Size Small
