Wake up at 5am in the morning to a blowing rain coming under your tarp and you'll know why an UQP is a good idea. That being said, at last years Florida Hang, Grinder showed me his cool setup. He uses a Dri Ducks poncho as an UQP. He ran cordage through channels at each end to attach to his suspension. I am adopting this method. Why? It has multiple uses. I can ditch the rain jacket, rain pants and pack cover. It will cover me as well as the pack, plus serve as an UQP. I'm also going to run cordage down both sides with cordlocks. That will allow me to cinch it up like the 2QZQ model. That's a great piece of gear for $15 bucks!
