I have a small otter box. It's got too much extra bulk for me to use for a kit container (I use a maxpedition M-2 in its place). However I often hike a particular trail that requires I cross a somewhat rapidly flowing river on rather loose rocks. I have fallen in more than once (usually when the dog gets too excited) and I find that the otter box is perfect for my digital camera when I take it in to this particular environment. <img src="/images/graemlins/grin.gif" alt="" />
