I have been using the product for about a year and a half. Overall, it does a decent job with sweat, but the issue is that firstly, even after so many washes, it still has a strong "plastic" smell. Secondly, from the first few washes, the threads started coming off. Lastly, although it is my size, the material under the armpit area is very hard, which makes it uncomfortable and leaves marks like a corset.
