All mentioned sizes are an indication. When, while measuring the different circumferences, different sizes are measured, the garment should be chosen in the largest size measured.
For example: if you measure size Medium at the waist and hips, but Large at the chest, it is recommended to go for the Large size.
We recommend making sure your gear has a snug fit. Sizing up might be comfortable when riding, but it’s also unsafe in case of an accident. Your local MACNA retailer is able to assist you in finding the perfect fit.
