See Our Proof
Leaks don’t take days off, and neither do we. Proof’s patented Leak-Loc™ technology protects against all of life’s leaks, both big and small, by holding up to 10 teaspoons (that’s 5 full tampons worth!) of liquid. Plus, our manufacturing is OEKO-TEX certified, our undies are Prop 65 compliant, and successfully tested for harmful substances.
We Know Leaks
From periods to pregnancy to postpartum to incontinence, the circle of life sometimes feels like the circle of leaks. As a company founded by three sisters, we’ve certainly had our fair share of leaks—who hasn’t?! That is why we created Proof, a line of meticulously designed and expertly constructed products that empower women to live life worry-free. No sneeze, period, or sprinkle can stop us!
