I bought a bunch of different rimless sunglasses.  These were my favorite by far.  They are very lightweight and comfortable.  They wrap around nicely so that peripheral vision is also well shaded.

My only complaint is I received a set with two nose bumpers for the same side.  They are mirror images of each other, so the textured side is on the outside instead of the inside on one side of my nose.  It isn't really noticeable, but it's something that suggests poor quality control. Took one star off for this.
