Rain, Hail, Snow, Whatever.
Brought the twelve foot version on a two week trip in Northern New Mexico. Over that period, we say everything from well over 100 degree days to 40 degree days with hail and awesome downpour. It was covered in mud, sand and whatever else we dragged it through. It never leaked, and never tore. We used two trekking poles and it worked just fine. Definitely going to by my own nine footer.
