I'm an avid CrossFit'er and find these shorts to combine the best parts of my favorite lifting, MMA-style, and economy shorts.  Slit in the sides is only a few inches up, velcro and tie closures are solid, and the material is good and thick.  They don't breath as well as some other fabrics, but for the price - I can stick to using them for shorter duration WODs, heavy lifting, and so on.  Highly recommend.
