- Set format: Check that you want a matching top and bottom base layer rather than a single garment.
- Fabric feel: The listed polyester and spandex blend gives a stretchy thermal layer, so compare it with the feel and fit you prefer for base wear.
- Colour: Pink is part of the described variant, so make sure it suits the intended use.
Before You Decide
Confirm the child's size, the top-and-bottom set format and the pink colour before choosing an offer. This thermal underwear set is aimed at cold-weather layering, so it is worth checking that you want a fleece-lined base layer rather than a heavier outer garment.
