Difficult to apply. Be careful with the sizing chart. It provides support but is also a bit uncomfortable because it doesn't fasten very well, so you have to fix it every now and then.

The product, if placed correctly on your body, meaning with the shoulders outside, fits well and keeps your torso where it should be. 4 stars because even though my size was large, I got extra large and it is still quite tight under the armpits. Generally, if you pay attention to the size, in my personal opinion, two sizes larger than the recommended one is fine

The vest is of mediocre quality in terms of construction, but where it is unacceptable is the size. According to the store selling it, I was supposed to get a large, but in practice, even a 3XL wouldn't fit me and I am 175 cm and 78 kg!
