First off, let me say this waist trainer surprised me in the best way possible. After receiving a faulty first product (which happens!), the replacement arrived in perfect condition and made all the difference.

The moment I put it on, I noticed how the U-shape breast design actually lifted without feeling like I was wearing medieval armor. The adjustable straps are a lifesaver - though one side kept slipping on my uneven shoulders (old injury problems).

Here's where it shines: I wore this during my 4-mile hikes through hilly terrain. Unlike other trainers that make you feel like a stuffed sausage, this one provided serious core support without restricting breathing. It stayed put remarkably well, only shifting slightly during extreme movements.

The zipper + hook combo is genius - no embarrassing pop-open moments mid-squat at the gym! Though fair warning: check those hook threads regularly as mine started fraying after a week.

Unexpected bonus? It's become my WFH secret weapon. As someone who slouches over a laptop all day, this constantly reminds me to engage my core. My chronic back pain has noticeably improved in just two weeks of use.

Washing tip: Despite initial fears (thanks to that first defective piece), it survived regular cycles just fine and dried crazy fast when hung up.

Size note: Ignore their chart! At 5'3" with a 37" waist, the XL fits perfectly despite their recommendation for 2XL/3XL. This seems to be a common issue among reviewers.

While not something you'll forget you're wearing (let's be real - no trainer is), it's comfortable enough for all-day wear. Just don't expect to sleep in it comfortably!
