Yes, several times. Once, it kept the rain out, but as with most single walls, we had some condensation issues. The conditions were horrible, though. Mid-30's , hard rain and heavy mist. We wiped down the inside several times with a micro-fiber towel. I had one small seam leak, which I fixed. I told LH about it, and they reimbursed me the 35 I had paid for seam sealing. We've had a night of rain in warmer temps and stayed absolutely dry. I must admit, I don't trust it as much as I do my BA Fly Creek, but the weight savings and ton of added room is great. We haven't had it in a driving downpour , like a violent thunderstorm. I imagine it will do OK, as long as the stakes stay in. The sil-nylon will sag a bit when it gets wet.
