Okay, so I've been using this neoprene sauna vest for about a month now, and here's my real talk review.

First off - the material is AMAZING. It's super soft and stretchy, but still gives that compression feel. I totally forgot I was wearing it after my workout once (oops!). The sweating effect is no joke - I definitely notice more sweat around my core area during workouts.

Now for the not-so-great part: SIZING IS WEIRD. Like really weird. I'm normally a medium in everything, but had to exchange for an XS to get the right compression. The sizing chart seems completely off base. Pro tip: order at least 2 sizes down from your usual size.

The zipper situation could be better - it sometimes pops open during intense workouts and the edges can pinch if you're not careful. Not a dealbreaker, but annoying.

What surprised me most? How comfortable it is for all-day wear! I work in healthcare and it actually gives great back support during long shifts. Plus, after a month of regular use, I can see subtle changes in my waist definition.

Final verdict? 4/5 stars - loses one star for the sizing headache and zipper issues. Would recommend if you're willing to play the exchange game to get your perfect fit!
