I was a bit worried about the fit before I got it as reviews suggested it was a bit on small side but Large fits my 58cm head perfectly. It's soft, it has a good shape, comes well down the neck and has a flap going round the back of the neck from ear to ear that the ties are attached to to secure it to one's head. As to the look, well I look better in this than in my expensive waxed cotton rain hat.
My head is 60 cm the hat is uncomfortably tight and not deep enough. the brim is a bit small. You could not wear a woolly hat underneath it. When will these chinese manufactures learn that the average european is bigger than the average chinese person? However if you have a small head then its OK for the price.
This is a great waterproof hat, very comfortable and warm. The only thing I would say is it comes up a bit small - I wear a medium size motorcycle helmet and I went for a large on here and it is tight... not uncomfortable but I have to yank it down to get it on! If you want it for very cold weather (eg. to wear a beanie underneath) go for a size up from what you measure. It is pretty warm on its own though!
I bought a jacket that didn't have a hood. I am outside for long periods in all weathers, this sou'wester is brilliant, waterproof, keeps the rain out of my eyes (unless the rain is horizontal which it often is) and stops it running down the back of my neck. It does appear as if I am about to arrive with the latest catch of herring, but nevertheless I recommend it.
