This is a Splash About swimsuit. Retail price: 6050 yen. Used once a week for about a year in swimming lessons. Therefore, it is slightly fuzzy and has small stains. Adhesive remains from a name sticker on the tag. This swimsuit is made of wetsuit material and was recommended as a cold weather protection measure for winter swimming. The child said they weren't cold. The size is set to 100cm, but it is a size M for ages 4-6. The size is not specified on the purchase site, so you may want to check it yourself. I cannot answer detailed size questions to prevent trouble. Color: Up & Away It will be compressed and shipped in simple packaging. Please refrain from purchasing if you are sensitive to used items or if you are looking for perfection, as it is stored at home by a private seller. Please note that there may be oversight of scratches, stains, etc., as it is judged from a layman's perspective. About this product: [Designed for both ease of movement and heat retention] The core of the body uses 1mm thick neoprene material (wetsuit material) with excellent heat retention, and the arms and sides use a soft and stretchy rash guard material. It protects the core of the body, which tends to get cold, while supporting the free movement of the arms and legs, making water play and swimming comfortable.

In addition, it is a gentle design that protects your child's skin from wind, sand, and scratches. It can be worn with peace of mind at outdoor pools and beaches. [Functionality ideal for swimming and leisure] The structure maintains body temperature, allowing you to spend comfortably even in environments where you are concerned about the cold. It is a versatile piece that is active in a wide range of scenes, such as water play, swimming lessons, beaches, and outdoor leisure.
