What to Compare Before Buying
- Size: The stated size is 140, so compare it with the child’s usual clothing measurements before choosing.
- Set format: This is a top and leggings set, which suits buyers who want matching base layers rather than a single garment.
- Layering use: It is described as slim enough to wear under regular clothes, so check whether that is the way you plan to use it.
- Fabric mix: The stated polyester and spandex blend gives a close-fitting stretch base layer feel.
How It Works
This is a close-fitting thermal base layer set. The top covers the upper body with long sleeves, while the leggings cover the legs. It is described as having a fleece lining and moisture-wicking properties, so it is aimed at cold-weather layering and active wear.
Before You Decide
Confirm the size 140 and the top-and-leggings set format before choosing an offer. If you want a base layer for sport or cold-weather layering, check that the close fit and fabric mix suit the intended use.
