I have not used it in the rain yet but it keeps the wind out. It fits - sort of - the sleeves are a little long and would be better with elasticated cuffs. The hood is a strange design, it is supposed to fold up into a pouch that sits inside the coat, this leaves a lump like a hunchback between the shoulders, why anyone could think this was a good idea is beyond me, the most comfortable fit is to leave it opened behind your neck. The pleats over the outer pockets are a good idea.
Truly waterproof coat! Tried and tested in British weather. I struggled to find something waterproof and resistant for when dogs jump not to tear the fabric, yet cheap enough not to spend a fortune for my dog walks - this coat is absolutely brilliant for this! In fact, it's so good, I will be ordering another one for my husband!
