Great buy! I use it at least 6 days out of the week along with the Sweet Sweat Waist trimmer. Guaranteed to be drenched when worn separately and with the waist trimmer.I ordered a size up. Could have gone up 2 sizes for comfortLooks really nice and helps me get my sweat on but the pants do run small. They were tightProduct arrived as stated. Glad that ordered 1 Size up or it wouldn't have fit. Pleased so far.This suit runs small I'm usually a size XL and ordered a 3X and fits good, good material. One thing I don't like as I'm exercising, and I start to feel the heat I get stuck on the suit. Not sure how to explain it. Example if I do jumping Jack's it doesn't really stretch to the point that I feel comfortable in it. Feels like it gets stuck to your skin and would rip.Great looking sauna suit. Able to run in it well…keeps the sweat pouring out! I went one size up after reading other reviews and it is a perfect fit!I bought this to wear in my sauna. I get out dripping sweat, and I'm not a sweaty person at all. I sized up 1 size according to other reviews, and I'm glad I did. Not a lot of stretch in the jacket. The pants I roll once at the waist, and they're perfect.SOY MEDIUM PERO LO PEDI LARGE Y ME QUEDO BIEN , CORRE PEQUEÑO COMPRELO UNO MAS DE SU SIZE. Me lo puse y se siente rápido el calor pero obvio debes estar haciendo ejercicio o moviéndote rápidamente para que comiences a sentirloBought this hot suit for my daily elliptical exercise and after 20 minutes didn't feel wet or hot at all .. so I immediately thought it's not working and decided to take it off. BUT when I took it off water was dripping from all over my body and suit ?.Very comfortable and the fabric looks quite good quality.I am a size 8-10 and after reading the reviews went for a size 12 which fits me perfectly. Totally recommend ?I use the jacket everyday when I walk the dogs, in the morning and evening. It’s an hour on a good pace so I’m sweating a lot ! During the home-gym-time I wear the jacket and the pants for my skipping rope workout, after 30min I can easily say the rain has caught me ? so yeah... It definitely works by increasing your body temperature which will lead to sweating. Do not forget about staying hydrated!Only size i am small and i have odered medium and trousers are great but top is tight but its amazing really nice quality very very happy thank uGreat quality but come up at least 2x sizes too small!! I ordered a large size 12-14 but feels more like a 10-12. Order bigger folks.It works and I sweat a lot even at first 15mins of exercise. It's just too big for me.
