To avoid the possibility of leaking one needs to make sure that Tena Flex briefs are snug around the legs. It is easy to accomplish, and it is the first ever product to allow my husband to sleep through the night without any discomfort.
This is the best product by far to use at night. I found it easy to put on while standing, in contrast to large adjustible briefs that can only go on in a horizontal position. The absorbancy is excellent, and it keeps the skin dry throughout the night.
