The rainfly for the EOS-1 has a 1-2 inch flap that is supposed to cover the zipper. However, it does not have velcro or other mechanism to secure it, so the flap is easily moved by the wind, which causes the zipper to be exposed to the elements and increases the risk of leakage into the tent.
I am 6'2". The tent is lightweight and easy to set up, there is enough room to sleep comfortably, but there is little room for sitting up. It is impossible to sit up without hitting my head and/or shoulders on the mesh and pushing it into the rainfly. When this occurred in the a.m., condensation under the fly got on my head and shoulders.
