Sizing Guide Lumi Active

The Lumi Active comes in three sizes: S, M, and L.

Consider your preferred fit and use when selecting your size. For a more sleek and form fitting style, as well as those whose intended use is under a helmet, we recommend sizing down from your typical size. 

Don't worry, if you select the wrong size we are happy to process a return for unused hats to swap out for a different size.
