The name "power hold" is definitely correct. These leggings have tons of compression and the fabric is thicker than normal leggings which adds to is and really hold everything in. I love the red color too, super bright. I am for sure buying more of these. I run in them and lift weights.
I ordered size medium and I'm 5'7" and 170 lbs, but they are definitely tight.
