In general we follow these size guidelines, but as you know, every little face is different, the age ranges are just suggestions. For example, our junior size fits a huge range of kids, sometimes as young as three, sometimes as old as teenagers. They are designed to start fitting most kids well around 4 years old, but no two heads are the same!
Our recommended sizes are:
Baby: ages 0-2 years old
Toddler: ages 2-4 years old
Junior: ages 4+ years old
Adult S/M: fits petite faces and generally women best
Adult L/XL: fits wider faces and generally men best
One of the biggest benefits of our flexible material, is that it gives lots of room to grow! Grab a carrying case & strap kit combo to keep your little sunnies safe, and to ensure a better fit on infants or kids growing into larger sizes. Comes with head strap and ear adjuster pieces! For juniors and adults, we also have our slip grip ear adjusters which help keep shades and glasses in place if slipping off.
