I carry a tube and a patch kit.... i have had to use both on the same ride, not often, but it has happened. I like the rema kits.....imho best quality. I write the date i bought the kit on it with a sharpie, and replace every couple of years. Small insurance cost for no surprises, but I have not had any issues with dried up glue....so far
