The first day out the box I wore them all day and they chafed in one spot but that was it. Just took them on a 9 mile kayak ride down a river and they were incredible. Even being in an out of the water all day they feel great and don't move around hardly at all and weren't chafing anymore. And I even got a sweet Chaco tan after only that one day on the river. Score. And a great price here. Best I've found.
