This is a pair of lined cotton hats from Hanna Andersson- I am listing this as a single item, but the price is for both hats, selling as a set. My twin boys have outgrown them. They are size Medium, the tag lists ages 2-6, I think 6 is pushing it, I would recommend for 2-4 year olds. The outer material is a knit cotton, one in bright red and the other in navy. The inner lining is jersey cotton in white. These hats do not have any staining, holes or damage, but you can tell that they have been washed. They work wonderfully as a liner under a jacket/coat hood during the winter, and as a perfect layer on their own to keep the head and ears warm during chilly fall and spring days. Thank you so much for looking!
