"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!"

    Great product and very well made!

    THE BAD 1st: I ordered the product but didn’t measure myself correctly and had to return for a different size. Not their fault, totally mine. Their return policy is “keep the product and get the correct item for 50% off or return the product back for a refund and start the order process over. Wasn’t a fan..again totally my fault though. THE CUSTOMER SERVICE however IS EXCELLENT. Literally answered emails in less than an hour, real time back and forth conversations and I got my refund ASAP.

    THE GOOD: great product not like those silver trash bag suits you buy from Wally World. You can tell the quality as soon as you take it out of the package.

    PRODUCT IN ACTION: I’m a little more than 3 month into a cut and decided to get the product to shed some water weight. Their transparent about letting the customer know your loosing water weight but sweating has tons of benefits for your skin. Plus, there is sound evidence of raising your core temperature to promote blood flow in stubborn areas to aid in fat loss. So I purchased one.

    Pictured is real life one day(6am-12pm) results. Again I’m pretty deep in a cut so I’m doing 2 a days in the gym. Morning cardio/afternoon weight training. These pics were taken with no food or water in my system, completely stripped down.

    Woke up 190, cardio 1 hour 187.4. cut grass 187. Power Nap went back to gym for weight training. Came back home 184.8.
