I would recommend not bothering with the Wilderness belt or biner. This is a perfect situation for a Dulfersitz (body)rappel. You can be finished with your body rappel before the person next to you has rigged up in a belt. Neither one is a particularly pleasant experience, but we are talking life threatening emergency, right?

There are lots of small,light backpacks (REI Flash 18, for one) that will be good containers for your stuff. You could carry it routinely as a small bag - my equivalent backpack has served for years as my carry on piece. A many-pocketed vest either fisherman's type or the more expensive Scott Evest, could prove useful, also a collapsible drinking container, about one liter in size. This being ETS, by all means throw in a signal mirror to make Rafowell (and me) happy....

Have a good time!
