Approximate measurements for our products are in the charts below. Every product has a different style & design so measurements may vary a bit from those in the charts. Please note this is athletic gear, so the Men/Women products have a slightly tighter “slim” fit to them, especially for Women jerseys. If worried about how Men & Women jerseys will fit, or are struggling with your personal measurements, we recommend going 1-2 sizes above your usual t-shirt size for a better chance of a good fit! For Kids Kits, the recommended size per age range is typically accurate. You may refer to the measurements, or go 1 size up if you believe the kid is bigger than average for their age. Please take your time to choose the right size, especially when the product is customized!
