Summer: 3 Season Yeti verus 40F Phoenix

[HillbillyHanger]

I'm a cold sleeper and have found I need something in the upper 60s, low 70s. I have a 20F quilt already, but I'm thinking about a dedicated late Spring, Summer quilt. I was only thinking about the 40F Phoenix, but I then wondered about the 3S Yeti. I know it's not a direct comparison, but I wondered if the 3 S Yeti wouldn't offer a little more functionality. My thinking is even though it's 3 season, it's a smaller size and would be easy to vent. With the 3 S, it might be a little more functional into the upper 30s. Anybody have any experience with both?

I use my 3-season Yeti a lot here in WV. It can get quite cold in the summer, or quite warm. I have used the Yeti in temps from 28 degrees to the 50's and was comfortable. I probably use the Yeti the most for long trips, since it has such a wide comfort range for me. Mine weighs 13 oz and that is with adding a secondary suspension to it so that it does not slide down the main suspension during the night. I use a short 3/8 Thinlight pad for my feet and lower legs.
I also have a 40 degree summer quilt the same length as the Yeti. I only use it into the lower 50's. I also use a 40 degree full-length quilt (1 extra oz down) and have used it to the upper 30's, but it is at its best in the mid-40s and up. Hope this helps you out.
