After testing this waist trainer for several weeks, I can confidently say it's one of the better options on the market - with some caveats. The neoprene material feels exactly like a wetsuit (which explains the intense sweating!) and provides serious compression.

The Good: The double belt system with steel bones offers incredible back support - I wore it during 3-hour cleaning sessions with zero back pain. The velcro is industrial-strength; mine hasn't budged even during intense workouts. For postpartum moms, this really helps pull everything back together while providing core stability.

Watch Out: Like several reviewers mentioned, it runs small. My 30" waist should fit a Medium according to their chart, but I had to exchange for a Large. The bottom belt does tend to roll up during high-intensity workouts - I solve this by wearing high-waisted leggings over it.

Sweat Factor: Oh boy does this make you sweat! After 20 minutes on the elliptical, there's literal condensation inside. Pro tip: wear a thin cotton cami underneath to prevent skin irritation from all that sweat.

Posture Perks: As someone who slouches at my desk all day, the posture support is phenomenal. The steel bones keep me upright without feeling restrictive. My chiropractor actually approved this for light wear during work hours.

Final Verdict: 4/5 stars. It delivers serious waist-cinching and back support, though the rolling bottom belt is annoying. Perfect for postpartum recovery, hernias (like reviewer Kim mentioned), or anyone wanting extra core engagement during workouts.
