What to Compare Before Buying

Size 12 is listed without a sizing system or garment measurements. Compare the sizing information with the child’s measurements, and consider how the set will fit beneath the clothing worn over it.

The polyester and elastane blend and flatlock seams describe the garments’ construction; they do not establish a particular warmth level or fit. For cold-weather activities, consider the other clothing layers and the conditions in which they will be used.

What Is Included

The set is described as a long-sleeved top and bottoms. Check the selected configuration if you expect any additional items.

Before You Decide

Confirm the size against the child’s measurements and check that the two-piece set suits the intended layering arrangement.
