I thought about getting those, but I wasn't sure they'd be dark enough in the middle of the day. I'm betting they would, but I was getting tired of ordering sunglasses and sending them back at that point. I went through 2 types of Tifosi's before I found the Slips. FYI - I have regular Tifosi sunglasses (casual wear) that I love, too. They were only $30! Same good quality lenses!
