Other brands of leakproof underwear I have tried have not been. Also, the plus size range for those other brands was smaller than they said the measurements were on their own website. Proof fits great and has kept me from leaking on my work chair when I cough or sneeze, and even on long trips and out hiking in the wild and doing tai chi. I finally don’t have to worry about embarrassing accidents. I can definitely feel the pad is there, but it’s much thinner than a normal pad and certainly better than Depends. Thank you Proof! You're the answer to a prayer I didn’t know I had.
