I've had this hat for a while now and I'm growing to like it more. There was a time when I thought there may be other hats that are better, and while that may be true, this one serves it's purpose so well, I find I wear it the most. It's one layer with no interior fleece or anything of the sort, but I wouldn't have it any other way. It's warm enough. I find I love it more and more.However, I do have a 3 layer thick 100% merino wool hat from Norrøna that is also very good. I use that for much colder temperatures.
"nice and big, might slip off small heads"
I got this hat a year ago in the "ireland" colors. It's really comfortable, quite warm. It looks really cool too.I have a lot of hair so I was really impressed that I can fit all of my hair inside of this hat. It stays on pretty well with all of my hair tied up inside. I will say that if you have a small head or no hair it will most likely fall off unless you are using ski googles or wearing a helmet. Please not that on the "ireland" colored hat the colors are yellow, green, and BROWN. I didn't know it was brown until it arrived. Just so you know. But yeah I love it!
