I bought this tent for the light weight, I didn't want nor need a two person tent. That having been said, if you're looking at this as a two person tent, my advice would be to look further. I sold a Hilleberg Rajd tent to fund this purchase and, so far, I have no real regrets. The Rajd was a single wall and I'll never, ever again own a single wall tent. Condensation is a huge problem with those tents; so far, not a problem with the Kilo.
As I said, this is definitely not a two person tent. My sleeping pad occupies almost the whole length of the tent and its width takes up the entire space at the foot of the tent. I have no ideal where Easton thinks another person could fit in! The "vestibule" is tiny; about all its good for is to put your boots in. Anything larger and you'd be rubbing up against the fly and inviting leaks. With just one person in the tent there is enough space on either side of you to place your pack and other things.
I am essentially a Hilleberg person where the fly is the tent and the canopy hangs onto the fly so I'm having some growing pains getting used to pitching the canopy and then attaching a fly. I had some minor problems getting the fly to pitch tight as would be needed to shed water. When I have the fly tight as I would like it the poles tend to bend a little off center but that's probably just operator error. It seems to me that I use all of the adjustment in the fly attach points to get a tight pitch. I did use the guyouts although the line adjusters are rather cheezy. I spent two nights in the tent up in the Cabinet Mountains Wilderness and it worked great in cool, damp conditions with no condensate forming on the inner side of the fly while all the leaves around me were quite damp. I'll keep posting as I learn more.
