Perfect fit

“I have large upper legs and most other products are hard to pull up. Your product gives plenty of room in the leg openings.”

The best hands down

“I have tried at least 30 brands, these are the best hands down. Not one accident since I started using these. Thanks for a great product.”

They actually cover

“Love that they actually cover the entire buttocks not just half of it, since I am a larger woman. Absorbency is good, too!”

Does not roll down

Nothing better for nighttime protection

“No other brand of adult diapers fit so well or block leakage. You can trust these overnight as well as for daytime wear.”

Discreet enough for work

“As a working professional who needs a discreet diaper, these are wonderful. They are quiet, comfortable and have a good capacity.”

Tabbed Briefs
Thomas H.
Verified buyer

Some of the best I've ever used

“I've had incontinence my whole life… The briefs that my insurance provides are extremely cheap and not good. The UnderX tabbed briefs are some of the best I've ever used. Very comfortable and holds everything.”

Wake up dry and sleep all night

“I am so happy with this product. This is the 1st time I have been able to wake up dry and sleep all night for years.”

Such a relief to have confidence back

“Rarely if ever do I get leaking… Actually went out with friends last week and changed only once. It was such a relief to have confidence back.”

Women's Pull-Up Underwear

Finally a product that lives up to the hype

“We have used everything on the market for my husband's nighttime needs… UnderX is by far the best we have tried. No longer needing a change after 4 hours has given him his good night's sleep back. And mine!”

Men's Pull-Up Underwear

She only likes this brand

“High quality product — soft, absorbent. My 97 year old mother has been using them for over a year… she only likes this brand.”

Women's Pull-Up Underwear
Paul O.
Verified buyer

Much less drama, cleanup and laundry

“Much better absorbency than the bigger brand. Wife has dementia and often states she is urinating down her leg but it's just a misperception. Her UnderX caught it all resulting in much less drama, cleanup and laundry loads.”
