What to Compare Before Buying
- Size: This set is size 12, so the key check is whether that matches the child’s measurements and intended fit.
- Fit: The compression-style, tight-fitting cut matters if a close base layer is wanted under sports kit or winter clothing.
- Set contents: It includes a long sleeve top and leggings, so compare it with any need for a single item or a different combination.
- Fabric blend: The stated 90% polyester and 10% elastane blend is the main material detail to compare if stretch or feel matters.
What Else You May Need
If the set is being bought for layered winter wear, check that the outer clothing leaves enough room for a close-fitting base layer underneath.
Before You Decide
Confirm the black size 12 set is the right fit, and check that you want a 2 piece base layer with both the top and leggings included. If the close compression-style fit matters, compare the size carefully before choosing an offer.
