Kamen Rider Gaim Pajama set, long sleeves. It's the right thickness for spring and autumn. Of course, you can wear it in winter too. It's not fleece-lined. I bought a size too big, so it was too large, and by the next year, my child was into a different character, so it was stored away without being worn. The neck size tag has been cut off. For children who love Kamen Rider, please wear it!
