I have found tape, shrink wrap, and other more permenant waterproffing to be more of an anoyance than neccessary. If I had my altoids tin wrapped in tape and the containance shrink wrapped I would never open the thing to retrieve a simple bandaid for a small cut while at work. This is because I would rather bleed that have to re-tape and re-shrink wrap the thing when I got home!<br><br>A viable solution has been with a simple 1 inch strip of inner tube, stretched and snapped around it. A standard innertube may be too small. Buy a 2.3 inch or larger mountain bike tire tube. <br><br>These 1 inch tube strips have many other uses as well. Like holding down straps, flopping equipment, ect.
