Kids' Baselayer Tops

Guide

Kids' Baselayer Tops

A base-layer top should move moisture during active play and feel comfortable during breaks. Compare fabric and warmth for your child's activity, using their current measurements.

Key points

The top should fit closely without restricting the neck or underarms.
The hem should still cover the back when your child raises their arms.
Quick-drying fabrics suit activity that works up a sweat.
Soft seams and a comfortable collar help beneath other layers.

What to look for

Question	In brief	Why
Which size?	In briefUse current measurements	WhyOversized sleeves slip and spare fabric forms folds beneath outer layers. Keep enough freedom to move.
How warm?	In briefConsider activity and breaks	WhyA very warm base layer can be excessive during energetic play. Add warmth through the outer layers when needed.
Does it feel comfortable?	In briefCheck collar, seams and cuffs	WhyThis layer sits against the skin. Let your child tell you where fabric feels scratchy or presses uncomfortably.
How is it washed?	In briefRead the care label first	WhyDifferent blends have different washing and drying requirements. Compare these with your routine.

Common questions

Should I buy a size up?

Choose from current body measurements and the size chart. Some movement room is needed, but excessive fabric should not fold heavily beneath other clothing.

Does merino feel comfortable for every child?

Feel varies from child to child. Let them try the fabric against the neck and arms. Compare a soft blend or synthetic fabric if necessary.

Does sport call for a very warm base layer?

Match it to temperature and movement. A lighter first layer may feel better during intense activity, with a suitable warm layer added for rest periods.

How can I check the cut?

Ask your child to raise their arms and bend forwards. Their back should stay covered, shoulders should move freely and cuffs should not slide over the hands.
