This BBL faja with the 3 hook-closure has a stronger compression. It has non-slip silicone straps inside the lace hem, which prevents the faja from rolling and a fully zippered crotch closure for easy access to the bathroom without removing the entire faja. Although I did not try this on solely bc I knew immediately that the zippered crotch would not work for me, I could tell this had better compression than the others that I purchased claiming to have double compression and it also appears to look smaller in appearance thus the size tip noted below. *Size Tip: Size is smaller than the normal size. So it's recommended to buy one size larger for the best fit. *Size Tip: Size is smaller than the normal size. So it's recommended to buy one size larger for the best fit.
