I have some CW-X stuff...2 pairs of their Pro Shorts. I wear them underneath my capri pants at the gym. I like the compression and support they give me...as I tend to need that with my "jiggly" legs. I wear a L in CW-X...however, I don't yet own a pair of LG NEO shorts (they are on my buy list) so I can't offer any comparisons in sizing. FWIW, I'm 5'6" & about 153lbs. When wearing the CW-X gear, I do tend to get that dreaded muffin-top...so I always wear a looser top to try and conceal that as much as possible. I have a lot of loose skin in my waist area, and at 45 years old...it's not goin' anywhere.
