Children's thermal underwear made of scuba micro-fleece (brushed micro scuba knit) is a two-layer winter base layer set, designed to protect your child from the cold and keep them dry during active walks or everyday wear.

• Material: scuba micro-fleece (a combination of stretchy micro scuba knit with a smooth outer side and soft fleece brushing on the inside)
• Fabric composition: 95% polyester and 5% elastane, so the underwear stretches well, keeps its shape after washing and dries quickly
• Temperature range: designed for harsh winter weather from 0°C to -25°C (32°F to -13°F)
• Gender: unisex (the model comes in a universal black color that suits both boys and girls)

• Thermoregulation and two-layer structure: thanks to a special fiber weave, the fabric forms an air layer that effectively retains body heat while preventing overheating during running or active play
• Moisture wicking: synthetic fibers don't absorb sweat (unlike pure cotton) but quickly move moisture outward, keeping your child's skin dry and minimizing the risk of catching a cold
• Stretch and comfort: the set fits closely and follows the contours of the body, so it adds no extra bulk under outer clothing (a sweater, snowsuit or jacket). The material is hypoallergenic, pleasant against the skin and "non-itchy"
