Kutting Weight SweatTech Neoprene Short Sleeve Workout Suit - Thermal Training Gear for Enhanced Sweat & Performance - Ideal for Gym, Running & Weight Loss Exercises

I'm 6' 2", 206lbs and a chest span of about 44".Have tried 3 different One-piece Sauna suits:1) Fighting Weight -- one piece sauna Suit XXL (my 1st)2) Kutting Weight -- one piece sauna suit (version 1.0) XXXL3) RAD -- one piece sauna suit XXLI've already reviewed the first one, which, along with Kutting weight were purchased here on Amazon. Bought RAD on eBay ( $5 cheaper there).Two others: "Authentic RDX Sauna suit" and "4Fit (aka ARD) Neoprene Sweat Sauna Suit" I'm yet to try. So, I cannot comment on them in terms of usage (only what I know from product description). But, the 4Fit (ARD) Neoprene Sweat Sauna Suit comes currently in 5XL, 6XL and Small. I inquired about this and was told they'd be restocking other sizes in about 2 weeks time.IMPRESSIONS:All 3 are made of DS neoprene. I believe the DS stands for Dry Suit. They all have that lingering rubbery neoprene smell. The more you wear and hand-wash it the more likely the smell will diminish.COLOR:All 3 are black in color.-- RAD sauna suit -- The stock photo seems to be (maybe it's the angle of the lighting) navy blue, but is actually black with red trims.-- Fighting weight & Kutting weight -- Both have black threading along their seams.Kutting Weight has a 1.0 all black version (with grey mesh arm pits and crotch area) and a 2.0 version that has a black-grey Lycra exterior with yellow stitch trims.-- RDX brand has 2 versions: An all black, and a black-blue combo.-- 4Fit Neoprene Sweat Shirt: Is all black with red mesh on arm pits and crotch areas.FLEXIBILITY:All advertise themselves to be made of "Extreme Flex grade Neoprene" that stretches and conforms to your movement. They do have some measure of "stretch" but this one piece suit shouldn't be used for extreme stretch based workouts like extreme Pilate, extreme Yoga and/or PIYO. Reason being that the butt area may not be able to withstand such stress without going beyond its elastic limit. This is when you'll start seeing a give/tear in the fabric at the lower rear area of the sauna suit. This happened to me with the Fighting Weight sauna suit, and I pointed that out in my Amazon review of that product. But knowing what I now know, I see that it's not exclusive to that said sauna suit. But one way to avoid this is to pull the shorts of the suit up high so that the inner thigh angle of the suit is as close to -- better yet, in close proximation with your inner thigh/crotch angle.Also, wearing compression shorts/tights underneath makes a world of difference too. And to the makers of these suits, they can add a "lag" in the fabric in these regions (arm pits and crotch area) which may also help.THICKNESS:All lay claim to being 3mm thick except for Kutting Weight which claim a thickness of 2.5mm. Now, I have no means of measuring empirically, but if I were asked, I'd say all of them are probably in that 2.5mm range as well.HEAT RETENTION:It's neoprene, so all of them will retain heat. The one caveat, which sets Kutting weight and 4Fit Neoprene Sweat Shirt apart from RAD and the others is the inclusion of breathable mesh material in the pits, and crotch region. If you're a male and worried about fertility issues based on the heat generated, then Kutting weight's mesh gives them that extra umph! factor. This is a direct hint to the RAD manufacturers -- if they're reading this. I haven't seen any other sauna suit that has this aside from these two I've mentioned.PRICE:This may turn out to be the deal breaker for many.1) Kutting Weight version 1.0: $79.992) Kutting Weight version 2.0: $99.003) RDX sauna suit: $71.744) Fighting Weight Suit: $61.795) 4Fit (ARD) Neoprene Sweat Shirt : $44.99 + $4.99 shipping6) RAD Sauna Sweat Suit:$44.00 (ebay) / $48.99 + $5.12 shipping (Amazon)DO THE MATHS:During your weight loss progression you'll find that you will drop a suit size as the fat melts off. Now if you were to use say a Kutting Weight version 2.0 for this, it will cost you $200 bucks for the 2 suits. Now if you were to go with the RAD sauna suit, you'd still be under $100 bucks for 2 suits.Think about that.OVERALL APPEARANCE:Now if your also about the aesthetics, and want to turn heads, or get nods of approval from the chicks and vice versa, then Kutting Weight version 2.0 is your suit of choice. It's a real looker! I'm sure those ones will definitely be flying off the shelves. But, if you don't give a damn, and all you want is something that holds in heat and makes you sweat, then anyone will do.FINALLY:3 reasons why you should wear an undergarment {compression shirt (short sleeve/long, or a plain T-shirt, compression tights (short, 3/4, or long) }:1) Sweat: Make no mistake, you will sweat profusely. This causes the suit to stick to your body such that you'll struggle just trying to get out of it.2) Stress tear: I mentioned this earlier. And compression tights help prevent this by allowing the suit to "glide" with minimal stress to the fabric.3) Skin Reaction: Some people may react to the neoprene material and may break out in small rashes (resolves within 24-48hrs). I have not experienced this while wearing the sauna suit, but did when I used a neoprene waist trimmer belt during workouts. Again, wearing a light T-shirt or compression shirt first before putting on the suit will prevent this.Well, I hope this helps anyone trying to make up his/her mind on which to go.PS: When choosing a size, take two sizes above your "normal" shirt size. If in the end it's bigger than what you need, then you can drop one size down.3/13/15 UPDATE: Just purchased the ARD (size: XL) one piece suit (ebay) and I uploaded a photo of the 3 sauna suits I now have. I stated earlier that my experience with ARD was limited because I didn't have it at the time of this review -- but now I do.It's honestly the closest thing to Kutting Weight in terms of having a breathable mesh. But it's overall quality -- though good, does not match those of Kutting Weight. Specifically, the finishing/thread trims is not as "sharp" as those on KW. A deal breaker? Not necessarily. But, you can't help but be impressed with the quality put into the Kutting Weight brand.To correct an earlier impression: I said you should go 2 sizes above your normal shirt/clothing size; rather just go one size up. I purchased a 3XL size which was 2 sizes above my XL and had to return it for a better fitting 2XL.UPDATE: 5/28/15I did mention that Kutting Weight version 2.0 is a real looker. Was sent one by the company and .... Wow! Seeing it in the real AND donning it on, I think I didn't emphasis it enough. So, when I say it's a looker, I mean IT IS a looker. Was sent a 2XL and I put it on clipped my pedometer in place and did a targeted 10,000 step walk (equals 5 miles) in the midday sun. I got A LOT of complimentary head nods and over the shoulder glances of approval from just about every female walking, jogging or biking the same bike trail I was on. I felt my chest puff out as I sauntered briskly with renewed confidence. I cannot over trumpet the "eye catchery" of this new version. The overall finishing and threading is far and away superior to the competing brands. So it's no overstatement when I say that it has that "designer wear" look about it.Anyway, I got to about 8,000 steps on the pedometer, so I decided to mow some lawn. By the time I was through I'd hit about 13,000 steps. Boy, was I sweating. After a 30 minute break, I felt the need to really put this new suit through some real stress test. And so I did INSANITY workout. The cardio was not my primary goal at this juncture, but rather to see how the suit held up when doing the pre and post -workout stretch. I'd also pointed out in the earlier part of the review that the sauna suits (regardless of brand) may develop stress tears in the butt region during extreme stretch exercises. I also said that wearing compression shorts/tights and shirts (any sleeveless or short sleeve kind will do) will help counter this (can't emphasis it enough). Now this new version held up AMAZINGLY well. Did not feel as overly snug as version 1.0. I'm suspecting this may be due to the extensive breathable mesh used in the groin area ( previous edition has smaller mesh area).And I was truly impressed by this because whether it was deep squats, lunges, Pilates, yoga ...it held up with absolutely no feeling of fabric strain in that region..I definitely recommend this version over the previous all black (with grey mesh) version 1.0..... And, oh, did I mention it looks great as well?
