Kids First Layers

Kids’ long underwear has certainly come a long way from the old-fashioned thermal union jack suit everybody once owned. Gone are the days of the thick and bulky one-piece children's thermal underwear replaced with today's long johns for kids, which are lightweight and high tech.

Winter Base Layers to Keep Your Children Warm

The fabrics utilized today for youth thermals for kids are moisture-transferring and contoured to fit every child's body type. There are many choices today in thermal clothes, layering pieces, and thermal underwear for kids—from the fitted or relaxed wick-away layers to the soft and warm fleece layers in both long pants and long-sleeve shirts.

Wick-away fabrics utilized in kid's lightweight thermal long underwear have revolutionized the industry. Cotton was once the fabric of choice for children's long underwear before it was determined that cotton, as it absorbs sweat, holds the wetness on the skin making the child cold. Wick-away thermal shirts and pants for kids transfer the sweat away from the skin, keeping the child warmer and dryer.

Shop WinterKids today for children’s thermal base layers and thermal clothing for toddlers.
