【Size】 White: No size listed (35 x 50cm) Navy: 90cm 【Material】 100% Polyester (Fleece) My child tends to get hot easily, so these were not used very often. The white one was used a few times when sleeping. It covers the feet and has a zipper, making it easy to put on. The navy one is a button-up vest. I only tried it on my child, so it's hardly been used, but it has been washed. I think the condition is good, but these are used items, so please understand that they are second-hand. Please check the notes in my profile before purchasing. Items will be compressed for shipping.
