I have a Beanie hat, I suppose most of us do, it tends to get worn when doing jobs outside when it is really cold, and it does keep my head nice & warm. I know this is not worn as a fashion statement, probably just as well, but so long as I am warm I am happy.
The Company is of course Thinsulate, and they have gained quite a reputation for hats, as well as g;oves & scarves. The name Thinsulate, is a Trademak of the 3M Corporation, the material was first introduced in 1979, and is a synthetic fibre thermal insulation. I suppost the nearest fabric to it would be Wool. Thinsulate can be machine washed, and left to dry outside, or thrown onto a radiator.
The hat is lined with a fleece-like material, and is very warm, but still allows moisture to escape, so you do not sweat too much. The famous Thinsulate label is on the outside, (nothing wrong with a bit of free advertising.) Being woven, the hat is elastic, so fits any head shape or size.
I will not state the price, as mine was given to me as a gift. It was a very welcome gift too. When not in use, my hat is normally folded flat, and kept in my coat pocket. It is not bulky, so is not noticable, and there is no weight to speak of. With the hat pulled down, it just covers my ears, vert useful in the Winter. I see a lot of these being worn, many covered with various badges, nice to see them being personalised. I suppose you Ladies could add a colourful Pompom to make it match a scarf.
I can thoroughly recommend these, and would not be without one nowadays.
