Gray Intersections Bike Helmet

A mathematically delightful helmet featuring a gray background and black shapes filled in at randomized intersections (kind of the two-color map theorem). This helmet is hand-painted with acrylics in our studio. It's also coated with a UV-protected varnish, making its surface scratch and water-resistant.

Each helmet comes with adjustable foam padding for the perfect fit. The S/M fits head circumferences 21" - 22.75" and the L/XL fits head circumferences 23" - 24.75".
