My Notch has done fine in heavy rain/lite hail. Even with some puddling around the tent, I stayed dry. Hail has splashed in the puddles and a couple of drops splashed up under the rain fly and through the netting. But no big deal and how often do you even see hail backpacking anyway? Regular and heavy rain, bone dry. Love this tent!! Was considering tarp/bug bevy combo but why when this tent only weighs 26 oz.
