✅ Subtle Customization – Premium gold foil print on back coordinates with left chest embroidered logo for team uniform compatibility

Smart Sizing Guide
Available in youth sizes 5-12 years (equivalent to XS-XXL adult sizing). We recommend measuring chest width rather than age for best fit – download our printable size chart here [link]. Note: Adult-size exchanges may incur 15% restocking fee due to specialized production processes.

Bespoke Order Policy
Personalized name/initial prints add 7-10 business days processing time. While we’re happy to advise sizing over phone (01708 320320), please confirm measurements before ordering as custom prints are non-refundable after first wear.

Ideal layering solution for school PE kits or winter sports programs – machine washable cold water treatment maintains print vibrancy through 50+ wash cycles.
