I first took this rain fly up on a snowshoe trip, since I bought it in January I was eager to use it. It did very well and kept my area free of snow drifts and clumps falling off trees. It was light wait and held up to the freezing temperatures. I then didn’t use it again for a few months due to a string of great luck with weather on my trips. Once I was finally able to see how it holds up to rain, it wasn’t as great as I had thought. I had a puddle of water on my pack when I woke up and it was due to a manufacturing flaw on the seam. The water proofing had been sewn on crooked and was allowing water to penetrate through the thread line. It didn’t leak during my snowshoe trip due to the dry cool conditions. I recommend a solid test before your return date has passed.
