I wish I had the rainfly for my trip to Guatemala. It would have saved me a lot of cleaning up of my Carryall Duffel's exterior after a hike to Montaña de Fuego. But now that I do have it, I am excited to take it on a trip where rain and dust will probably be part of the itinerary. I like that it has a pocket to store it when not in use and the hooks that it has to keep in place on top of the bag. Perhaps one thing to make it even better would be to include a loop on the pocket to be able to hook it on a carabiner. Overall it is a nice and lightweight rainfly to better protect you gear.
