Let me start by saying this sauna suit is INTENSE. The first time I wore it for a 30-minute home workout, I looked like I'd jumped into a pool fully clothed. The heat-trapping PU material really does its job - maybe too well!

The adjustable waist belt is my favorite feature. As someone who carries weight in my midsection, the compression feels supportive rather than restrictive. I actually found myself standing taller while wearing it - bonus posture improvement!

Now about that smell other reviewers mentioned... yeah, it's real. Out of the package, there's a strong chemical odor that made me hesitate. After two gentle hand washes (following the instructions carefully), it's about 80% gone. Pro tip: Add some white vinegar to the rinse water.

The mesh armpits and crotch are lifesavers! Without these breathable panels, I think the suit would be unbearable. They provide just enough ventilation to prevent that 'plastic bag' feeling while still maintaining serious sweat action.

Size warning: This runs SMALL. I typically wear Medium but needed Large for comfortable movement. The XL seems to fit like a standard Medium based on multiple reviews. If between sizes, definitely size up.

After three weeks of use (alternating days), I've noticed my post-workout muscle definition improving faster than usual. Is it magic? No - but the extra sweating does seem to help with water retention and temporary slimming.

Biggest con besides the smell? The zipper sometimes catches if I'm not careful when dressing quickly between work and gym sessions. The safety buckle gives peace of mind though.

Final verdict: If you can handle the initial odor and size quirks, this suit delivers serious sweat sessions that can boost your fitness results. Just don't expect miracles without putting in the workout effort too!
