Does the Shiro 4 have a rain fly?
No it does not - just make sure the windows and vents are zipped shut. I have had this tent in the rain, and it does not leak. One thing that you should be careful about is the fact that there is no floor. You sleep in "sleeping pods" or "sleeping compartments."
I have really enjoyed this tent, and I think it would make a good decision for a basecamper, family sleeping tent.
Not like a traditional tent. The structure itself is he rain fly. The pods sit Inside and don't touch it. I'm not sure how well it will work In a downpour.
