I bought this with the matching jacket and I must say I am not disappointed with this product. The instructions on the bag say to hand wash item but I put it in the washing machine on delicate for a couple of minutes, comes out like new.I actually ordered these pants along with another Neoprene pair of workout capris from another company. I ended up returning those and keeping these because the others were shaped a little oddly and also a bit shorter than expected, though I did really like their color design. However, these also didn't fit as expected which I will explain..I kept these because the fit was more flattering than the others and I like having the side pocket, which is important. These also stand true to having a good high waist. What's interesting is that they actually fit me more like capris than pants. When pulled up to the right spot, the bottoms (which were very tight at the seam, probably because they're meant to be pants and fit around ankle area) came to my mid-calf. To be fair, I am on the taller side 5'10" BUT I haven't ever had this issue with garments labeled as "pants" vs "capris" in over 15 years in the fitness industry and involvement in modeling (which basically equals a LOT of workout bottoms), so I'm thinking it's just a Neoprene-material/style issue. I would say if you're taller than 5'8" with average to long legs, you will find that these qualify more towards capri-style than actual pants leggings... (I will try to add a picture to this review once I have time).That said, if you're shopping around for Neoprene "sauna" leggings or capris and are on the taller side, I would only go for things selling as full pants.. because you'll either get long capris or short pants. For example, those other capris I tried and returned were literally around my knees and super unflattering.As for the "sauna effect" - honestly, I don't feel as though these make me sweat a lot more than usual.. I just feel like they make the sweat more noticeable when peeling the pants off (yes, peeling.. off AND on). But I can tell they keep my legs warmer in the cold weather than other leggings, so decided to keep them for morning winter walks or hikes outdoors (as opposed to more intricate workouts, in which case it would just feel like I have a wetsuit on).Be aware, these aren't meant for comfort (read wetsuit statement above) or to favor high mobility and movement. They would work for that just fine if you wanted to use them as such, but they are stiffer than typical leggings of any other material. Obviously, as they are Neoprene-lined. As for if these are "loud" because of the material, they may make more noise than regular leggings.. but not as much as a typical tracksuit. I really wasn't bothered by any noise with these.Another thing - these do "loosen" a bit as you wear them during the day to have more give.. but I only noticed that in the rear after a day where I was up and down and sitting more than usual. The waist and definitely calf/ankle area stay super tight. Oh and as for the smell, again, the closest thing I can compare these to is a wetsuit. So nothing crazy, but they definitely have a light rubber-ish kind of smell to them which didn't bother me much.Hope this review helps someone out :)I liked the way these pants fit, medium fit perfectly. And I could feel the sweat drip down my legs so they worked!Nice to slip on and off after taking a walk.The pant fits overall. However the legs need to be longer. When I pull them up, they rise about 3" above my ankle.I am 5'7.5". I have long legs.I’m using the neoprene Capri for a fitness competition to drop some water from from ski and burn a little more fat.Works well.But loose on the legs.I’m 120 lbs 5’3”Waist 25I got the Capris ones - they fit great in the waist but terrible in the legs - the legs are way to big and do not fit at all. They are too wide and the gap between pants and leg defeats the purpose of the pants - they are supposed to fit tight so that you can sweat more.ALSO .... THEY SMELL REALLY BAD - the chemical smell from them is nauseating - I actually had to wash them on very mild cycle (you are not supposed to) - the pants are fine but the smell is still there. I am worried that those chemicals will seep into my skin and body.AND ..... THEY ARE VERY NOISY - they are really loud when you walk in them - luckily the gym plays music but when I got home you could really hear the noise.Would not buy them again - sorry to say - great idea - bad execution.El material está muy padre. La talla pedir la que eres/usas. me guié por la tabla y me sugería XL y me quedó grande de la cintura y cadera.Soy de muslo grueso y cadera ancha (de la pierna, si me quedo bien).La M seria ideal para míI got the order before the expected date and I used it on my first work out ... the sweating was amazing!! The only fault I can pick is that they fit perfectly on my waist but found them to be too wide on my calves . Apart from that they are pretty goodI’m not sweating as much as I thought and the reviews I read. I m happy with the the host shapers I bought which I sweat a lot I would not recommend this to any of my friends and familyMuy padres la verdad, puedes llevar tu cel contigo y no se moja para nada de sudor, son cómodos...
