Since 2006, the domestic water-strap pants have been the most confusing, and the number of miscellaneous brands has increased to dozens. The main reason is PVC products, because this product has more fabric production factories, and the capital is not used much. A few people can form a small workshop, but after all, the production capacity and variety are limited, often only a series of three or five varieties, if especially in 2008, affected by the financial crisis, export export raincoats and boots factories have a lot Turning to the water pants. For a time, the brands are mixed, the imitation goods are crowded, and the dealers everywhere are at a loss. In addition, some manufacturers do not put the quality of the products in the first place, but they are all fashioned to make the waterproof pants into fashionable products, fancy and flashy. The original role of the loss of the original, the thickness and quality of the material of this bottoming will be greatly reduced in the service life.
