I bought these leggings to see if they could help me manage my POTS. I originally bought the small which was way too small, but was able to easily exchange for the large. I like the leggings - they're comfortable, and the mesh fabric keeps me cool. They do have a tendency to roll down if I bend over, but I would say they're better than other 2XU leggings I've tried in this regard (i.e. the form stash range). They're pretty high-waisted so they do provide some abdominal compression. Overall a very good compression option, particularly as the weather warms up as these leggings are designed to keep you cool!
