Very good belt for waist support. I have had surgery for an L4-L5 intervertebral hernia and when I wore it I felt safe to lift an object around 20 kilos. Waist circumference 98 cm, I took the medium, maybe the small would also fit.

Very good belt for lower back support at the gym.
The velcro it has for fastening is very strong and gives you confidence (at least now that it is new).
In bench exercises (e.g. incline presses), the pads that are on the back (EXTERNALLY, not in contact with the waist but with the bench), at first seem to have a strange feeling. However, as you get used to them, they create a slight lordosis in the waist during the exercise, which gives more safety. For €16 it is a great deal.
I recommend it.

A basic waist belt, I would have preferred it a bit firmer with more support for the back, which is why I gave it four stars.

I do not have much experience with such belts. I bought it after doing some research on reviews, avoiding leather ones due to some negative comments, and chose a synthetic one due to hernia and exercise with moderate weight. It is quite stable but it does pinch a little, obviously requiring a lot of attention and moderation for someone with such issues. Otherwise, it seems to be of good quality. The only thing you need to pay attention to is the sizing chart, which I posted in a photo.
