Kids Fleece Lined Long Underwear Set Long Johns Light Blue 5-6 Years

Why it's a great deal

• Premium Fleece-Lined Fabric: Our kids thermal underwear set has a soft, brushed fleece-lined interior that traps body heat to keep your kids warm on cold mornings, snow days, and chilly nights. Made of 90% Polyester and 10% Spandex, this lightweight base layer feels smooth against the skin and delivers cozy warmth without the bulk of heavy winter clothes, making it a go-to thermal set for kids all season.

• Warm and Moisture-Wicking: The breathable, lightweight fabric wicks sweat and moisture away from the body to keep boys and girls dry and comfortable during recess, snowball fights, sports, and active winter play. It locks in warmth while reducing heat loss, so thermals for kids stay cozy and sweat-free from school drop-off to bedtime.

• Stay-Put 4-Way Stretch Fit: This top and bottom set pairs a long sleeve top with matching pull-on thermal pants in 4-way stretch fabric, so these long johns for boys and girls move freely as kids run, jump, and squat without tightness or pulling. An elastic waistband and elastic cuffs give a no-ride fit under outer layers, and the tagless design keeps the thermal underwear itch-free on sensitive skin.

• Occasions: Our kids thermal underwear set is ideal for school days, skiing, snowboarding, sledding, snow play, ice skating, winter camping, hiking, outdoor sports, and cozy days at home, plus everyday layering under winter clothes. Keep boys and girls warm and comfortable through every cold-weather adventure all winter long.

• Size Options: Available in sizes kids thermal underwear set 5-6 years, thermals for kids size 7-8 years, kids long johns size 9-10 years, base layer size 11-12 years, and kids thermal set 13-14 years. This set runs close to the body, so please check the size chart and choose by height and weight, or size up for a roomier fit that works for both boys and girls.
