The question is, what time of the day are you going to wear them, and how much urine do you usually produce during that time? I checked out their website, they have two types for men. One says "absorbs at least 50ml". The other says "absorbs at least 100ml". Now if you look at a few sites that sell adult disposable diapers, they often rate those by how many HUNDREDS or THOUSANDS of ml they hold.
