Breg doesn’t usually make an XXS brace, but with a little extrapolation, I figure this would fit someone with a thigh circumference of 27-34 cm (10.5 in - 13.5 in) and a calf measurement of 29-33 cm (11.5 in - 13 in). It’s marked XXS, so it might even fit a child. It’s very nearly new. Please check the pictures, as they are part of the description. Make sure to check my other items. I will gladly combine shipping if you find something else you’d like. I ship most items through USPS Priority Mail.
