I like the reflective stripe down the sides, and the half-moon shaped mesh on the bottom:
Here's a closer up picture of the reflector. You can also tell by the side view that they are rather loose fitting in the legs/butt. But the waist is elastic so it is fitted. These are size 4, my normal size at Lulu.
This is the close up of the front view with the elastic band and tie. I think the rise is a little lower than the Speed shorts.
The back fits loosely too, and there is a pretty good-sized zipper pocket on the left butt cheek:
I don't know what my hand is doing there lol:
