my son liked it...he got it for his birthday this week!
you can buy (better, actually) them on the web, just the hats, or hats with matching moibus strip scarves.. (about $70)just google klien bottles.

i made mine/his after looking at the ones for sale, and mine came out pretty good, but i think i could do better if i was inclined to make another..
(they are very warm, since you end up getting a double layer of knitting over most of your head.)

oh, don't do this! if you get me started posted about knitting here, you find i post more about knitting than id do food!(my knitting boards are so much nicer that here--they have a catagory for food post, but AWAD doesn't have a catagory for knitting or food!
