I finally got around to going to sunglass hut and they happened to have some Twenty's in stock. I tried them on, but felt that they didn't have the wrap of the fives squared. I tried on a pair of fives squared immediately after, and they looked like they wrapped my head much better. There was only one pair of Twenty's, so I wasn't able to try on another pair to see if it was maybe a stretched out pair. Can anyone confirm that fives squared have a tighter wrap than Twenty's?
