Choosing the Correct Version

The same style is described in several colours and sizes. Before choosing an offer, check the age size, fit and colour so you select the version you actually need.

Before You Decide

Confirm the age 13 years size, the regular fit and the black colour before choosing an offer. If you want a looser underlayer rather than a close-fitting compression style, compare the fit against your preference first.
