EHWwrote a review of CW-X Insulator Endurance Pro Tight - Women's on December 22, 2015
Familiarity: I've used it several times
Fit: True to size
I'm 5'4"ish and around 120 lbs and the small fits me. The tights take a bit longer to get on. I find it most effective to sit down and put each leg in up to the knee, then stand up and pull up the rest up and adjust the seams to fall where they're supposed to. I don't see any difference in the way my muscles feel during or after my runs, but I do like the feel of the compression as I find them to be no more than just really tight tights than to provide actual muscle support. I got rid of the drawstring as it's thick and flat and I don't think anyone would actually use it to cinch the waist any tighter than it already fits.
