Cycling apparel is almost always smaller in fit than regular clothing, so please refer to the sizing charts below as a guide. If the fit is not quite right, we offer free exchanges for incorrect sizing or style choice.

Is your stomach larger than your chest? Use your stomach measurement instead. If in between sizes, usually, it is best to choose the larger of the two.
