Like every other damn hiker, my wife and I will be using NeoAir Xlites during our 2017 PCT hike. We're planning on cowboy camping wherever possible and tarping the rest of the time.
We're going to pair the pads with a UL bivy such as the Borah Gear Side Zip, and I'm curious to know if we should also bring a ground sheet in order to further protect the Xlite from punctures.
Have you paired this mattress with only a bivy with no issues? Or is extra floor protection needed?
