My husband is a Pancreatic Cancer survivor (seven years!) and had a Whipple Surgery (if you know/you know). Whipple completely rerouted his digestive process and, as a result, he suffers from gas, sometimes gas attacks, which can be embarrassing. We didn't know there was a thing as medical grade underwear, or really anything that could help. We have tried one or two other brands, but Tootles is our go-to brand now. We both thank you for this superior product. It is meeting the need -- a need we are grateful to have because he's here - seven years later. Thank you.
