Temp rating of BPL Cocoon 60 quilt

Hey Gary, I don't have any experience with that exact system you've mentioned, but I have used the UL 60 with my Montbell UL Down Inner and can push these 2 to about 45 degrees give or take. IME the UL 60 is great by itself when the temps will not dip below 50. When the temps do dip lower insulated layers and some good R value below are a must for me. One thing I've noticed is that the narrow design of the UL 60 quilt can leave me feeling slighly restricted when i add a *puffy* layer to boost my system; I have broad shoulders so that contributes to this as well. Test your system in your backyard or somewhere with a simple exit strategy to see how your body works within your system. That way there's no risk and you can test the quilt life out and see if it's for you=)Have Fun

Similar experience on my part. Good to around 60F by itself. 50F with some insulated clothing.

Thanks, guys, that helps. And you think the 180 quilt will do maybe 40 F by itself? Ryan used the 180 on that Arctic trek, assumedly with additional insulating layers. I'm not sure what temps he dealt with. But if the 180 can only do 30 F with extra layers, then maybe the 5.5 oz. weight penalty of my Hydrogen bag is warranted, if for no other reason than its compressibility to save space in the pack (of course there's the down vs. synthetic argument, which is less of a factor here in in CO than the Cascades).

I would consider myself cold-natured and with a balaclava on and silk longjohns I have been amazingly comfortable in my Cocoon 180 down to 35 deg. and in just my underwear up to about 55 deg..

I have had similar experiences with the UL 180. I have used it to the mid 30s comfortably with with just a balaclava and long underwear in a bivy with nightlight and full length thinlight. I have pushed it even further down into the low 20s and was comfortable, but need to wear extra layers, montbell Thermawrap parka and pants, and used my downmat and full length thinlight in a bivy.

The pad that you use the quilt with makes a huge difference in what temps the quilt is comfortable at.

I too have had similar experiences. I've had the 180 down to about 28 degrees with balaclava and insulated top and was warm inside a tent. I've had the 60 down to about 40 with the BPL balaclava and cocoon pullover inside the GG One and was comfortable though I think I would've got a bit chilly if it got any colder. As Aaron noted, the cut on these is a bit narrow so if you're going to be sleeping under a tarp it might be worth looking at a bivy as well. (Unless you don't move much at night.)
