I was looking for a new 3 in 1 Waterproof coat to replace a no longer waterproof item. Not yet had the chance to test how waterproof it is neither has it been cold enough to wear as a 3 in 1. The waterproof outer is understandably a bit large when worn on its own but there is plenty of room for wearing jumpers, fleeces etc. I am hoping this will be fully waterproof as I work outdoors in all weathers. It is a bit longer which is useful in bad weather. I bought it at a discounted price which was very handy!
