"Comfy Sports fit" and "PRO snug fit" optional, please check the color reference. Riders who could not match their body datum perfectly to the measurement spec(e.g. height in, but weight out), please send the seller an email to get professional support, it's the best way to avoid the frustrated size exchanging when you find item does't fit. DO NOT pick the size base on the size of your T shirts or jeans, cycling wear is with tighter cut than the casual wear.
