Quick Summary
The Coralup kids compression base layer set is a 2-piece pink thermal underwear suit in size 4-5 years. It is presented as a sports base layer for wear on its own or under other sports clothing, and the product text names both a top and trousers as part of the set.
The set is described as using polyester-based wicking fabric with spandex, and as having lightweight, flatlocked seams and four-way stretch. These are the main details to compare if you want a fitted base layer for a child and need the size, fabric blend and set contents to match.

What to Compare Before Buying

Before You Decide
Confirm the 4-5 years size, the pink colour and the 2-piece contents before choosing an offer. If you want a child’s base layer, also check that the fitted compression style and fabric blend suit the intended use.
