The product does what it sets out to do, it makes your hips and butt smaller.. But I've noticed for the slightly bigger guy it can be a nightmare. But, the pocket for packing is great.
Although I've said they work, I do have some warnings.
(ftm) At 5'9 and a bit bulky, these shorts aren't long enough for my knees and so they clench where they end. (Yes I had myself measured, I bought the right size.) I struggle to conceal the where the band pushes into my skin on both legs. It can be a struggle to readjust and make sure those shapes don't show, even under jeans. Not only that but pants have the tendency to fall off the smooth texture. (they keep falling down unless you wear a belt.)
If you plan to add a full length top binder to the mix, bare in mind the smooth fabrics will clash and cause all sorts of rolling.
