Let me start by saying this waist trainer vest is a game-changer for my workouts! The neoprene material really does make you sweat 3x more—I felt the difference during my first HIIT session. It’s like wearing a portable sauna around your core, and I noticed my back stayed straighter too, which is a huge plus for posture.

However, sizing is TRICKY. Like many reviewers, I had to size down (normally an XL, but the L fit better). The double belts and front hooks let you customize tightness, but the compression is VERY front-focused. If you want full waist/back support, this might not be your jam.

Comfort? Surprisingly great! No digging wires or muffin-top bulges (finally!). I’ve worn it under hoodies for errands—zero visibility. But fair warning: the shoulder straps rubbed my arms raw during intense cardio. Thin material = lightweight but not super durable for daily abuse.

Best for: Light-to-medium workouts or wearing discreetly under clothes. Skip if you’re curvy or need serious back support. For $30-ish? Solid buy—just check that size chart twice!
