Impregnation products tested - Rain - so what?

A good impregnation prevents jackets, shoes or tents from getting soaked in the rain. The waterproofing sprays tested are universal products that are suitable for various textile fibres and for leather. The waterproofing detergents, also called wash-ins, are primarily intended for outdoor and functional clothing. We tested how well the products repel water and keep dirt out. A comparison is worthwhile: the test winners withstood significantly more downpours than the losers. There is also a price tip among the best sprays.
