Kids' Cotton Thermal Underwear Set, Letter Print Base Layer

This cotton thermal underwear set brings a candy-inspired letter print to everyday base layer wear, featuring a round neckline designed for children aged 3 to 8 years. Made from 95% cotton with a soft treatment, the set offers a keep-warm function suited for the autumn season, making it a practical base layer for cooler days.

The ordinary fabric thickness keeps the set comfortable for regular wear under clothing, whether for school or everyday activities, while careful stitching with trimmed loose threads in obvious areas adds a neat, finished quality.

Available in a range of colors including pink, gray, coffee, khaki, light blue, dark blue, and purple, this thermal set offers sizing from 110cm to 180cm to suit growing children and students. Its letter detailing and soft cotton fabric make it a fitting choice for warm, comfortable base-layer wear during the colder months.
