Kewlioo Sauna Shirt for Men - Heat Trapping Sweat Vest, Sauna Suit For Men, Compression Workout Sweat Suit for Gym, Workouts

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.

Shirts run smaller but they work great

Great product must go up in size for a perfect fit I’m 6.5” in height 310 fit a 4xl fits good length is Perfect. Not fat but got that beer belly.

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.

Deifnelty works as intended. Wore it for the first time on my work out and I was in a puddle of sweat. I was nervous about sizing after all of the reviews but it fit perfectly. Follow their sizing chart and you can't go wrong.

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.

I have previously brought there 3xl one before getting these. Once I find that one I will leave a detailed review on that one. As for this it works idk why ppl keep sending these back. I feel like they didn't want to give it a chance cause it did say on the product description to go up a size cause they're going to be very tight fitted to you. So if your normally a medium then do large or xl, but that still feels too tight for you then maybe you should not get this product. Cause I brought 3xl im normally 2xl transgender woman but I read the description fully and understand what I had to do. So I eventually changed it to 2xl now cause I just started to do some heavy work out. So these are super good for me I love these so much they're super nice stylish. For those who didn't want to give it a try I do understand that it might be to tight or maybe it sensory issues with it. I am sure that there is a possibility of a better product for you 😊😘😁

Bought the 3 pack cause I really don’t feel like washing the same shirt to get in the sauna. Haven’t actually tried them in the sauna yet to give a functional review, but the sizing is as everyone described. Inconsistent at best, one shirt fits tight, one fits just kind of slim, the other is baggy. All tried on within seconds of each other. If you don’t mind them all not fitting the same these are for you. If you want consistency, this is not the brand for you.
