>>209532Ushanka.com, if I recall correctly, sells authentic, high quality hats. You should be good to go.
>>209536Generally avoid bright colors, and if something looks like a knockoff of another brand or is too cheap, it will surely be poorly made.
However, all cheap products are not bad, I own one of Kangol's ushanka hats (a steal at $68), and have worn it throughout fall, winter, and spring for the past eight years or so. I have a couple nicer ones, although I'd consider it my "beater" hat.
