Familiarity: I've used it several times
I will admit that this tent is a bit on the heavy side but I always split my gear with my partner.
But recently, esp. for the summer, we just carry the stakes, the fly, and the poles. The fly provides adequate shelter in high alt. For low altitude areas, I can only imagine anybody who uses only the fly to be tortured by bugs and mosquitoes.
The poles and stakes are light and the fly looks pretty awesome when deployed. Kind of looks like a shelter for a colony on mars! lol
The vents help minimize condensation but they don't have a mesh to keep the bugs out but again, it's not a problem when use for high altitudes. I just wish they had some kind of screen if I ever used it in a forest.
In regards to weather, this tent can withstand it as long as you have it properly staked to the ground.
I have never gotten wet yet and the bathtub design gives me that confidence that I will still stay dry even when I set up in a puddle.
