When you purchase a raincoat, this doesn’t necessarily mean that this coat is 100% waterproof. This is why you should always pay attention to the waterproof rating for your raincoat. The waterproof rating indicates how waterproof it is. The higher the rating, the more water pressure the material can withstand. European legislation states that a fabric is waterproof as of 1,500 mm. Is the waterproof rating for your coat somewhere between 0 and 1,500 mm? Then this coat is only water-repellent, making it only suited to lighter, more mild rain.
