"Great vests for sweating it out - I bought from Kewlioo 2 vests when I starting out in the gym to tone and lose fat around my middle. They really do work as I lost 12 lbs in 6 weeks and my middle is fairly well-toned now!"
Suzan D.
"Product was well made and came on time. The sizes fit well I love the material. I saw results from my sauna vest in literally one day. I hope to see other products like it!! Thanks so much and I have recommended it to people..."

    Usually when I wear a heat trapping shirt I feel the sweat and it’s like a slip and slide in my shirt. With this product I was comfortable, felt nothing and even questioned if I was sweating. When I took it off there was so much sweat! It was comfortable and definitely works. I cannot wait to try the tank top!

    I ordered a 2xl after reading some of the reviews. I am an xl and the 2xl still feels a little too tight. I still wear it and I like how it doesn’t slip up just need to lose a little more weight so it’s not so tight. Overall great shirt makes me sweat like crazy.

    I wear small and I purchased small, it fits perfectly, nice and tight, might need help when it’s time to take it off because product does what it says, makes you sweat like no tomorrow. I love it.
