I purchased this new, unused item here, but I ended up not using it. Since it has been stored at home, I've listed it as "like new." The size is listed as L, but it's approximately 80-90cm. It seems like it could be used for about 6-12 months, depending on folding the sleeves, etc. This is a navy rash guard with UPF 50+ for warmth, a long-sleeved and footed design to protect your baby. - Color: Navy - Material: UPF 50+ fabric - Features: Warmth - Size: ~95cm - Design: Long-sleeved, footed Original price: Approximately 6000 yen ★ This is the warmest baby wetsuit with a soft fleece lining. ★ Made of high-quality neoprene with high heat retention, and the lining uses fleece that is gentle on baby's sensitive skin. Babies and toddlers cannot move around in the water and tend to feel cold faster. Therefore, the warm-in-one, which covers the arms and legs, is the perfect item for long periods in the pool or when the water temperature is low. ★ The softness of the fabric and the large opening on the back make it easy to change clothes. ★ The lining of the warm-in-one does not absorb skin protection creams, etc., and can be kept on the skin as it is, making it an ideal wetsuit for children with skin problems such as eczema or those with sensitive skin. ★ UPF50+ processing prevents UV rays while protecting against cold water and cold. Please note that it may be compressed for shipping, so please understand that there may be creases. Thank you for looking.
