My first Tilley is still my favourite, It was bought in Toronto on a once in a lifetime holiday in Canada.
It is built like a Tank and is of heavy canvas similar to a lorry tarp. It is 100 percent waterproof and really
indestructible. I have been fortunate enough to be able to afford some of the more recent lightweight
ones, which are great for summer use, especially
the ventilated one with the open mesh round the crown but it is not for heavy rain. Like someone on
here said, the woollen Tweedy one for winter is really great in the cold, and it has a flap inside that comes
down over your forehead on cold days plus a protective flap that can be brought down over your
ears. Great.!! My other favourite is an Aussie hat
in leather, bought in Ambleside in the Lake District,
North England. All of them need tying on in windy
weather. Can't say a word against Tilleys though.
