Taekwondo Reversible Chest Protector

WTF style reversible chest protector (hogu), double sided, with Red and Blue coloured sides. The cut is somehow smaller than a usual taekwondo chest protector cut, so size 0 would perfectly fit 4-5 years old children. Size 1 and 2 would fit children ages 6-9, depending on their size and complexion. Size 3 is for a bigger child and smaller adult. Size 4 would normally fit an adult of average size, and size 5 is for bigger taller taekwondo practitioners.
