I have condoms in my kit, also, and share in the reservations I've read here. I've noticed that some forumites have FoodSaver or similar vacuum packers. I cut off a JUMBO hunk of bag stock (12" x 18") and put my kit in the southwest corner of the bag before vacuum packing. Then shrink and seal. <br><br>The "tails" of the bag fold up easily around the tin. They're held with a jumbo rubber band cut from a bike inner tube (also a fire starter). When you need your kit, just cut off the smallest corner of the bag needed to release the vacuum and slip your tin out, and you now have a pretty large water container. There's excess plastic, so roll up and tape/tie to carry.<br><br>
