I bought the Crestone to replace my Kelty Ultralight of 10 years, which has a very similar design. The 2-pole tunnel design with pointy ends is perfect for a 6'3" person like me, and it seems to be unique to Kelty. The reason I upgraded is becasue the ventilation wasn't good enough to prevent condensation in the ultralight when I move from the dry Sierra Nevadas to the wet Adirondacks. The Crestones ventilation is amazing. Well worth the upgrade. Yet, Im a little disappointed with it otherwise. The droop between the two poles is so deep that it takes away space from the inside. I also worry about rain/snow accumulating on the top of it. The panels of the tent are strangely not cut such that the zipper doesn't wrinkle near the corner. Youd think Kelty would've figured out by now how to cut fabric to make curved surfaces smooth. The other thing that took me a while to figure out is that to get the fly to not touch the tent near the foot and head triangles. You have to stake out the vestibules really far away from the tent by tying a 3-foot line to the stake loop and then staking the end of the line, thereby leaving a gap between the ground and the bottom of the vestibule. The tent is much better than its predecessor, but I look forward to the next version, where hopefully they will fix these problems.
