How do I find the right incontinence product for my individual needs?
Because Overnight Absorbency Underwear comes in S/M–XXL (28–80″ waist). Also available: Maximum Absorbency Underwear (4 Cups), Adjustable Tabbed Briefs, 3 levels of incontinence pads, and 2 levels of booster pads for extra protection.
How do I tell which side is the front and which side is the back?
You can tell which side of Because underwear is the back by looking for the size indicator. The side with the size indicator is the back.
Can I use my HSA or FSA for Because incontinence products?
Yes! Incontinence products are generally eligible expenses under HSA & FSA plans. However, it’s always a good idea to check your plan’s specific requirements.
How do I know if I should switch to adult diapers from bladder protection pads?
If you’re noticing frequent leaks, dampness despite pad use, or needing to change pads often, it may be a sign that your current protection isn’t enough. Adult diapers offers more coverage & support, helping you stay dry & confident longer.
Do Adult Diapers Expire?
No. Because Incontinence Underwear does not expire. The date on the package indicates when it was manufactured—not an expiration date.

Overnight Absorbency Pull Ups for Adults
To me this is the best adult diaper to buy. I haven’t had any leakage problems and it does hold to 6 cups of liquid. I would recommend this for adults with incontinence.

Perfect for long flights and limited bathroom abilities
So I am a petrified flyer and have to take long flight frequently . I pass out at every take off no matter what I try to combat it. I purchased these for that. Yes, my bladder is out when I am. Like during a seizure my bladder just lets loose when I go unconscious I do prepare before had but have also lost consciousness during turbulence so it’s just a smart thing to do. These absorbe like crazy. I wear a move snug pair of Lycra pants so no leaks and have yet to have an issue. Life savers!
The package was damaged. Two of the hand sanitizers open and we’re all over the place. –
Best product
This item holds a lot more water. Great product. It’s helps my husband tremendously. Thank You

Better than Depends
Because works better for me than Depends they have more protection than Depends. My only complaint is they still leak if you sleep on your side, they are somewhat expensive. To me they are comfortable and I do not notice a smell. I would buy again. Update … I have since purchased another package but am VERY disappointed. In this package all of the diapers spilt up the side at the seams as soon as you put them on . I did not have this problem before but am now leary about ordering another package.

No leaks. No rash.
Comfortable and no leaks . Much better than the Fit-Right brand.

Good product but not for men
These are probably the best pull ups I’ve found so far, but not well designed for men.Positives:I wear a 46 pant, so according to the size chart, I should wear a large, almost XL. It says if you are between sizes to size down so I went with large. They fit well and stay put. The absorbancy and capacity is pretty good, and these are the only pull ups I’ve found with standing leak guards.Negatives:In order to accommodate male anatomy, the product needs to be wider in front so it can come up around the privates more. Moving too much will pull those leak guards down too far and allow leaks when flooding happens. Also, being that urine comes out in front on men, the absorbant material really needs to come up higher. I find urine is hitting right at the top of the absorbant material unless the pull up is carefully adjusted first.Overall, this is a good product that just does not work for me and I suspect will not work for most large men.

Great absorbency
I purchased these for my mom because the store brands were not absorbent enough. She was waking up wet or soiled during the night or having accidents during the day and messing up her clothes. These diapers work perfectly and she has had no mishaps with her clothing during the day. While she still wakes up at night, its for a diaper change, but no leaking is occurring.This is a great product that works!

Good and Bad
A bit too thick for me. Ends up putting pressure on the perineal area due to bunching up of the pad. Great absorbency if you don’t have to sit for long time.
Karen Winters –
I bought these for nighttime wear for my elderly mother-in-law. They are by far, the best fit and absorbency of anything else she has tried. (And she has tried 3 other kinds from the local medical supply store, as well as Kirkland brand) No more doubling up of cheaper pull ups, no more leaks and extra laundry the next morning.The higher price and import fee is worth it for this Canadian customer. We are now buying the case of 80, which will save us some money. I’d highly recommend these.
Susan –
The underwear fits snugly around legs and lasts through the night. Best adult absorbent underwear around.
Susan –
Since I received the last order in December 2025, the quality of these have gone from a 5 star to a 1 star. They no longer absorb fluids, it sits on top of the pads and ends up having the urine running down your leg! I have had to reinforce these with absorbent liners and they are the only thing that seems to actually hold any liquid! DO NOT BUY THESE! Unless they go back to the previous format I will never buy this product again!!

very absorbant
