A convenient body warmer for regulating a baby's body temperature. Made with wool yarn that has high heat retention, a soft and fluffy texture, and a high-quality luster. The shoulders are sewn using a "linking" technique, which is only possible with knitwear. This makes the seams softer than regular sewing, resulting in a comfortable fit. ■ How to Wear ・ Wear it between the underwear and outerwear when it's cold. ・ Can also be used as a vest. ・ Can be worn until around 10 months old. Material: 100% wool Country of Origin: Made in Japan Purchased at Shinjuku Takashimaya. Retail Price: 8,800 yen per piece Frequently washed.

It seems that just wearing one keeps them warm, and they started sleeping well.
