My son's head is large and mine is medium. Very soft flexible weave fits perfectly for each of us. I would believe that the same would be true for a size small. My son's beanie was a birthday gift and he finds it so comfortable that he often sleeps with it on. Also, the 3 brightness levels are a great feature.
You don't want someone staring at you with the brightest level on. Very powerful!!
