One set, top and bottom, in a fine waffle knit that does the thermal job properly: trapping a layer of warm air next to the skin while staying slim enough to disappear under jeans, uniforms, and snow pants.

The top has a crew neck and cuffed sleeves that do not ride up inside a coat; the bottoms have cuffed ankles that stay above boot tops instead of bunching. The inside face is brushed soft — because a thermal layer a child refuses to wear warms nobody. Cut in a shared fit for all kids, in heather grey that washes with everything.

Kids thermal underwear set — the details that matter

Fabric & construction

A cotton-rich waffle knit: the little pockets in the weave hold warm air against the skin while the garment stays slim. [Exact fiber percentages to be confirmed with supplier — editable placeholder.] Ribbed cuffs at wrist and ankle, an enclosed waist elastic, and a printed label complete the set.

Care instructions

Wash cold or warm with similar colors and dry on low. Overdrying flattens the waffle loft, so pull the set out promptly.

Good to know

Buy thermals by the coldest week, not the average day: the set is midweight, so on genuinely bitter mornings it wants a fleece over it inside the coat. Worn under pajamas it also lowers the heating bill argument at bedtime — a layer warmer than another blanket argument.

Drawer note: thermals live nine months of the year in storage, so wash before putting them away and store flat rather than vacuum-bagged — the waffle loft is the warmth. When the first cold snap is forecast, move the set to the main drawer a week early.

Questions about this pack

Is this set for girls, boys, or both?

Both — the cut is a shared kids' fit with a crew neck top and an elastic-waist bottom. It appears in both our girls' and boys' collections because the design is identical.

Will it fit under skinny jeans and uniforms?

Yes — thermals only work when they sit close, so the set is cut slim with a fine waffle knit rather than a thick fleece. Under regular school clothes it adds warmth without visible bulk.

How warm is it, honestly?

It is a midweight layer suited to cold school days, outdoor recess and winter sports as a base layer. For deep-freeze temperatures it is designed to be worn under a mid layer, not as the only insulation.
