No Decoloring and Pilling：The boys base layer set washes well in the machine without shrinking or running color. Still comfortable, warm and ultra-soft after many washes
Thermal Fabric with Added Thickness: Our long johns for boys are crafted from a blend of 95% Polyester and 5% Spandex, featuring a soft velvet interior for warmth during cold winter days and cool nights. These long underwear are designed to be lightweight yet warm, ensuring your child stays comfortable without added bulk.
Four Way Stretchable：The stretchy fabric of kids long underwear offers flexibility no matter how active you boys are. The wide-band design of the pants allows us to avoid tension and discomfort, effectively protecting the delicate skin of children
