How To Measure:
CHEST: Measure around the fullest part of your chest.
SLEEVES: Measure from the centre back of your neck, over the shoulder and down to the end of your wrist with arms relaxed at the sides.
BODY: Measure from the highest point of your shoulder down.
If you're in between sizes, go with the smaller size for a tighter fit and the larger size for a looser fit. If your chest and waist measurements correspond to different suggested sizes, order the size indicated by your chest measurement.
