Opinions on the best gear to take for a planned overnight bivy (canyoneering trip)? Planning to do the full Imlay route end of June, so staying at the crossroads area. Usually I've taken 3-4 lb small tent, sleeping bag, and pad when backpacking. However, I haven't acquired any lightweight gear for a night while canyoneering. This will be a first. Understandably, you need to take minimal equipment. I've heard some just say take a light tarp and sleep on the ground (bug and scorpion prevention?), others take a lightweight bivy sack (prices range from cheap to several hundred bucks). There are even fancy ~1lb weatherproof small tents. What do you use? What do you recommend? All opinions welcome.
