Size: M (2-4 years old) 【Reference Sizes】S (6 months - 2 years old) M (2-4 years old) L (4-8 years old) Mittens, suitable for a wide range of children. 【Cold Protection & Insulation】Uses high-performance padding material with excellent insulation and breathability, providing high heat retention. The soft, warm inner lining offers high insulation and a fluffy, comfortable feel, keeping your child's hands warm all day long in any weather conditions. 【Easy to Use】Features adjustable Velcro straps for easy on and off, allowing children to quickly adjust to their wrist size, preventing cold air from entering twice. Velcro straps also make it easy to put on and take off. 【Water Repellent】The outer material is water-resistant, breathable, and water-repellent! It repels water droplets in light rain. High performance prevents water from entering from the outside! Great for various outdoor activities such as snow play, commuting to school, cycling, mountain climbing, skiing, watching sports, and winter work. (Water-repellent, but not completely waterproof. If used in a wet environment for a long time, we recommend applying a waterproof spray.) 【Loss Prevention】Features a joint function to prevent children from losing one glove, which is common. Also, joining them together when putting them in a bag eliminates the hassle of searching. Shipping is planned via Yu-Packet Post Mini, but this may change.
