Mizuno Breath thermo 1/4 zip collar long sleeve Bike or Running Shirt size XS

Mizuno Breath thermo 1/4 zip long sleeve Bike or Running Shirt size XS. Size tag says Medium but it is much smaller than that and doesn’t have a huge amount of stretch so fits like a small or extra small. Please Check Measurements in pics. . In excellent condition I never wore it except to try on. I have a breath thermo top I’ve worn for ever, keeps you warm without making you hot, absorbs sweat and doesn’t rub. Great for running, hiking, winter sports, skiing, snowboarding, bicycling,
