Saw all the great reviews and understand the desire to get rid of the cotton undies. Liked the idea of something I might wear for workouts and/or for day to day wear. And like the quick wash/dry idea for possible traveling light. So bought one pair to try. At the same time bought the Addidas Climalite Performace 2-pack to try. Both felt similar in that they were lightweight and stretchy. Like the feel of both. Wore both a few times before deciding I liked the Addidas better. The ExOfficio did tend to ride up a good bit. With the Addidas I never think about having them on. That's what I want. No riding up the leg nor wedging where it shouldn't. Could just be the fit of one vs the other being better for me personally. So while I like the ExOfficio, I am buying more of the Addidas which I like better and are less expensive.
