What to Compare Before Buying
- Size: The listed size is 8-9 Years / Size 26, so compare that with the child’s usual fit rather than relying on age alone.
- Fit: The set is described as compression-style and stretchy, so check whether a close layer is preferred under sports kit or school clothes.
- Waist and seam design: The wide high waist and flatlock seams are useful details if a smoother feel matters under outerwear.
- Use case: It is presented as a base layer and thermal underwear set, so it is aimed at layering rather than being worn as outerwear.
Before You Decide
Confirm the child’s required size, since the key variant here is 8-9 Years / Size 26. Also check whether you want a close-fitting thermal base layer with stretch features and a black finish. If you need a different size or a looser fit, a different version would be the better choice.
