Really nice robe! I just threw it in my cart to get free shipping when the price dropped to $5, but I wished I bought more than one now since it went out of stock. The inside is polyester, while the outside is a jersey material. It doesn't get really static-y like other polyester robes, and there seems to be minimal pilling after washing it a few times. It's cozy and warm without being too bulky. I also like the length and design of the sleeves. Not too long or too short. The length hits at the knee for me, as pictured. (I'm about 5' 4".) Would definitely buy again.
