We've tried to develop a variety of sizes for everyone who want's a specific fit, but we also recognize that many people just want a standard size that can be adjusted for most faces.
Our Regular size is our most common and practical size, it fits most men and womens face's comfortably, and the adjustable straps allow you to make any final adjustments on your specific face.
A small size would be a petit face or someone looking for a much more fitted look.
And extra-small would be specifically for children.
