I've used this a few times since around 2019. The size is SS. I'm 155cm tall and have a slightly slender build, and it fit perfectly. The inside is mesh, so it was comfortable without feeling sticky. I never had any leaks while using it, but it's been stored away for about 4 years, so there might be some aging. I did a quick water leak check when I washed it in the bath before listing it, but I didn't apply water pressure for a long time, so please be aware of that. There's some dirt in places, but I think it will come off with a brush. The dirt was hard to see and remove when wet. Would this be suitable for children or petite women?
