Be Flexible!
Great product that works very well. The material inside the shirt adheres to the skin to warm your core. So it’ll cling to the skin, making it seem hard to remove after you’ve been sweating. I’m normally a size large. I ordered 2XL and it fits me fine. So definitely order a size or 2 up. If you like compression, order 1 size up. If you like looser, order 2 sizes up. I don’t see this being a good product for folks that are over 250lbs though. You need to be a bit more flexible to remove the shirt without stressing the material which could potentially rip with too much force. Overall, I love it and it works very well for me. Thanks.

Best sweat ever
Already wore two now them! First wasn't so great as it was to cold outside...second day though.... was just the right amount of sweat one can expect from a suana shirt. I generally lose 1lb during a jiu jitsu class and I ended up losing 2 during a light class. Fits snug just like I like (I wear a large t-shirt and it was just smaller than that). The material while thicker was still comfortable to wear under my gi, but also comfortable for just wear around the house. Styling fit was also amazing.

The size chart is off
I am 5’10, 205 lbs, and bought xxl and xxxl. The xxxl fits like a normal t-shirt. The xxl is snug especially around the biceps. Other than that it the product help increased my sweating. I would recommend going two sizes above your normal fit if you want comfort.

4X fits like a 1X absolutely misleading product | Way Too Small to Be Useful
I ordered this sauna shirt in a 4X, expecting it to fit comfortably for workouts, but what showed up was nowhere near the size it claimed to be. The tag says 4X, yet the fit is closer to a 1X at best. I could barely get it past my shoulders, and once I did, it felt like trying to squeeze into a wetsuit made for someone half my size. There’s compression, and then there’s simply being unwearable, and this one falls hard into the second category. I normally fit a 4X and KNOW what a 4X should be like. The material itself actually seems decent, thick and smooth on the inside with a stretch that should have made it comfortable if the sizing were even remotely accurate. The zipper looks solid, and the overall construction gives the impression of a quality item, which makes the sizing issue even more frustrating. You can tell it’s designed to make you sweat and trap heat effectively, but none of that matters if you can’t move your arms or zip it up without feeling like you’re about to rip the seams. I double-checked the label and the packaging to make sure they hadn’t sent the wrong size, but everything matched the order. That makes me think the entire line runs extremely small. If a 4X fits this tight, there’s really no chance someone who wears a smaller size could find their correct fit without guessing several sizes up. It’s disappointing because I wanted to like this one. The idea is great, and I’ve used similar gear before that worked really well, but this one misses the mark completely. If you’re planning to order, be ready for a serious size shock. I’d say go up at least two or three sizes, assuming they even make that many options, or skip it altogether if you’re looking for a realistic fit. There’s no point in a sauna shirt that turns into a struggle just to get on, and that’s exactly what this feels like. I wanted something to help elevate my workouts, but instead I ended up with something that barely fits over my chest. Definitely a one-star experience from start to finish.

Really good fit
Extremely comfortable, it is tight at first then it is a very good fit and works up a good sweat.

Sweat
Not true to size. You should between sizes larger for it to fit properly. Other than that it does allow you to sweat.

Shirts are nice. Two of three are defect. Returlable doesn’t work.

I bought the Small T Shirt and when waiting, I read the reviews to size up and thought it would be too small. When it arrived, I was surprised to find it was too big. I looked the size guide online and, as I have a 29” waist, it would be big. I went to return it but couldn’t find an equivalent available online which would have fitted. So, I wore it under a compression top and it worked well. I’m disappointed that I couldn’t get it in the correct size but workaround was very effective.
