Let me start by saying this sauna shirt is NO JOKE when it comes to making you sweat. I wore it during my usual 30-minute HIIT session, and I was dripping like I'd just run a marathon. The heat retention is incredible - it really does feel like wearing a portable sauna.
The upgraded fabric is a major win compared to old-school neoprene. It's stretchy yet supportive, with no annoying itchiness. I particularly appreciate the padded neckline that prevents chafing during burpees and jump squats.
Now for the elephant in the room: SIZING IS WILD. I normally wear L but had to go XXL based on reviews, and it's still compression-tight. The struggle getting it on/off is real - imagine wrestling with a very determined octopus. Pro tip: Apply baby powder first!
The targeted compression zones work surprisingly well for core support during heavy lifts. However, if you're between sizes or value easy on/off, this might frustrate you.
After three weeks of use (and careful hand-washing), it's holding up well with no odor retention. Just know what you're signing up for - this is serious sweat gear, not a casual workout tee.
