I find that Curad fabric ones are the best for me. The adhesive is good, and it's even all the way around the pad. They stay on through quite a bit of abuse, and soap and water.

They're cheap at WallyWorld, about a buck a box. I buy several boxes at a time and put the contents of two boxes into one to save space. Cheap helps, because I tend to get so dirty when I'm working outside, and have to change them frequently because the Filth Factor. <img src="/images/graemlins/crazy.gif" alt="" />

But if you need a pretty tough waterproof bandage TAPE to use with pads or other non-adhesive bandages, look for the rolls of Waterproof Adhesive Tape. You may have to get them from regular pharmacies, as discount places like WW often don't carry it.
