MERINNOVATION Kids Merino Wool Base Layer Set 220GSM Long Sleeve Thermal Underwear for Boys and Girls Midweight Top & Bottom

The merino wool in this blend helps regulate body temperature in both directions - providing warmth when still and breathability when active. Every set carries OEKO-TEX Standard 100 certification - independently verified and safe for all-day wear. No itch at the collar. No stiffness at the knees. The merino component actively helps move moisture away from skin during activity, reducing the heavy, clammy feeling that builds up in all-cotton thermals. Comfortable through extended wear - this is how merino wool behaves naturally. The top and bottom work together as a thermal base layer under ski jackets and snow pants, or stand alone on mild days for hiking, hunting, school, and travel. The flexible cut supports a full range of motion without bunching or pulling. Kids stay focused on the activity, not what they are wearing. Each set arrives packed in a paper gift bag - ready to give for birthdays, holidays, or any occasion that calls for something practical that lasts. Machine wash cold under 104°F (40°C). No shrinking, no fading, no pilling. The softness is in the fiber - not a surface finish - so it holds wash after wash.
