Fits well and makes swimming a joy. Great product.

I swim 5 ocean miles daily on Kauai where winter water temps are 73. I have a WT60 sleveless but it's not warm enough so this WT 50 is fantastic, it fits like a glove, i wear a small i'm 5'7" 140 28waist. It's like it was tailor made for me. No water flows through. It keeps me toasty warm for 2.5 hours of swimming breastroke. It does take some adjustment as the SLIGHT positive boyouncy is increased in the salt water so it gives an increased resistance workout. I.e. you feel sore in arms more than without a suit but the tradeoff is WARMTH!! I can't say it would keep you warm in 50-60 degree water but if you have enough fat than why not. I love it and i look super HOT in it. I am very impressed with Aqua Sphere products as i also use their seal mask. This suit is also VERY easy on and off and dries quickly. And as a bonus if you start to get chilled i find a good pee will add another half mile of warmth!  Highly recommend to anyone. I will say the fit is VERY snug which is good but if your borderline with size you may need to go up a size.

I (we) use this product for water skiing. It is awesome. Good for water temps in the mid 60's and maybe a even a little cooler depending on the air temperature. It is so flexible unlike using a dry suit. I have recommended it to several of my(our) fellow water skiers.
I have not found any downside. I have had mine for about a year and have used it many times and it is still in great shape. My spousal unit used his the first time and could not  stop thanking me for going ahead and gettting him one.
