Wool-blend knit sweater with penguin embroidery. I think it's easy to put on because it's soft and not thick. I removed the tag, but I received it as a gift and never wore it because the timing was off. - Design: Penguin embroidery - Size: 80-90cm - Material: 83% wool, 11% acrylic, 1% nylon I have never worn it, but it has been in someone else's hands and stored at home, so please refrain from purchasing if you are concerned.
