Blue Fleece so warm that it keeps you warm during the winter. It is very big, and it keeps shape no matter who wears it, so even a skinny little girl can appear like a big bodybuilder. It has a polyester layer underneath which guarantees the temperature, and when you add the strings that can close the bottom, you are ready to go into the mountains. It is in great shape and doesn't wear any marks of long usage, so it can serve you for a long time.
