My husband and I just returned from a trip and two products that worked were the protective overnight underpants and Heaven Scent Disposable Incontinence Diapers Bags.
The underpants prevented leaks through hours of plane travel. They absorb an amazing amount of fluid and the wearer never feels wet and soggy.
The Heaven Scent bags are ideal for odor free disposal of waste associated with incontinence care. They are sturdy and don't leak. I used them throughout our stay in a hotel and kept embarrassing odors to a minimum.
I use both of these products at home also in daily incontinence care and couldn't manage without them!
