Kelty Flight 2

I've used this tent for the last 3 years, totaling upwards of 100 nights including one of my cross country cycling tours, so I'm very familiar with it..

Pro's:
It is LIGHT! Wow, is it light. And it packs down incredibly small. I pack it with the footprint, but without the poles. The tent will fit in a Therm-a-Rest stuffsack (slightly larger than a Nalgene), and the superlight poles go in your pack or pannier.

Con's:
Bring a tarp if you're expecting rain. It doesn't like the sky; water pools just above the 'brow' pole and below the rainfly, eventually seeping through. Condensation is an issue only half of the time. The vents on the sides really help. Although the vestibule is large, it slants down very far and you can't get too much tucked underneath there... I've taken it in snow, it holds snow well (with a tarp covering it) and it does a descent job in the wind, but damn the water. It'll ruin your trip. Also, Kelty needs some color. If you like your tentmate, fear not, if you don't, prepare to cuddle. The feet are narrower than the head, so no head-foot sleeping, sorry.

Wish I could think of more. Not entirely water/condensation-proof. EASY to set up. Smallish door. Rainfly thing goes over the mesh in a split-second. Unless you like sleeping under a tarp, I wouldn't recommend it.
