New Disc Recs?

I found a hole in my flex disc so even if i wanted to i cant use it anymore, i did notice that sometimes my disc would push out and or be hitting my bladder and overall it was just uncomfortable, im looking for one that is slightly smaller, and the rim is just as soft as the flex if not softer. I did some researching and found that the part that holds all the liquid is pretty thin and i like that compared to this other brand i got from amazon (it looks generic but i couldnt even use it bc how hard the rim was) Any information helps, thank you!
