What to Compare Before Buying
- Size: This version is for 10-12 years, so compare it with the wearer’s current clothing size rather than guessing from age alone.
- Fit: It is a compression fit top, so check whether a close fit is what you want from a base layer.
- Colour: Sonic Yellow is a strong, visible colour choice, so confirm it suits the intended use and preference.
- Sleeve length: This is a short sleeve top, so compare it with the amount of arm coverage you want under outer layers.
Before You Decide
Confirm the 10-12 years size, the Sonic Yellow colour and the short sleeve compression fit before choosing an offer. If the wearer needs a looser layer or different coverage, a different version will be a better match.
