Pika, I have a prolight long. I used it about hmm 6 or seven nights before I switched to a hammock. Nice pad and I always liked the fact if it punctured I still had a bit of foam between bag and the ground. I just coud not keep it under me in a hammock! I still have it as I hope to go to Arizona next winter. My brother is in Chino Valley. I want to hike into the Grand Canyon. I have been there several times ,but not backpacking. I dont think there will be many trees to tie off from in the canyon?
