      I love love the product and I love their professionalism when it comes to returns always order a size bigger as the do run small. But when I say I give them 11 out of 10 I mean it

      Worth the money

      I started out with the size 3xl last June. I am now wearing the size Large a year later and think I’m ready for a medium. I have purchased every size down from 3x so that tells you how well they work! Well worth the money! If you’re worried about the price…I have been able to resale all of mine with no problem on the PM app.

      Worth the money

      I love the way it snatched my entire abdomen and back. Good quality material and no weird smell. It really does make you sweat A LOT. If you have a short torso, this one isn’t for you, try another waist trainer in the brand. I’m 192 lbs, waist 31 inches,and the sizing suggested XL and I tried to cheat it by getting a large, it zipped up, but it was too tight on the waist, it would have been very uncomfortable to workout in. The support team was very helpful in getting my large exchanged for an XL. They are true to size, so please don’t size down, because it’s gonna be really snugged.
