Keeps you dry. I have mine in a permanent spot because it was near to impossible to set it up finding placement on ground and trees. With that bit said it will completely keep you dry in torrential rain.
Worked great. Used it while SUP camping the Chipola River. Kept me dry through rain and very wet mornings. I can’t comment on the durability yet but it appears and feels like it will last. The guy lines are a nice extra, wish there was some instructions on the best way to use the guy line hardware; but a bowline and a cinch knot work fine. Good product look forward to using in the future.
