Amazing! The support your backside and hold you in great. I am a female who purchased the Mens XL because I am 5'5 at 240 with a whole lot of "junk in my trunk". I run pretty slow but boy is it heavy lagging all of this around. These were my choice after I heard so many other women in my run group speak about them and I am hooked. Now, I don't want to wear anything else. What was fine before I got them, just wont do anymore.
