Double Bubble Plus Yeti 3/4 20 deg??

[bbanker]

Hey Guys n Gals! So I have a Warbonnett BlackBird double layer 1.6 and have a 3/4 Yeti 20 deg that I use with a small square of Ridgerest. For an upcoming trip that it may be between 10-15 degrees, I have a Double Bubble XL pad that I was thinking about using to augment my usual setup which is usually good to 25-30 degrees for me. I'll likely be using a Marmot 0 degree bag for my top insulation, used like a quilt. Anybody have any experience with a setup like this? I tend to sleep a little cold myself and know it is very subjective, but just wanted to see if anybody else had done a similar setup?

bbanker, I would say you might be okay but it really is tough to say. If you're a cold sleeper, it might be a little chilly. I found insulation like the double bubble goes a long way for me and it's all I used on the ground for years (3 layers). If I was to suggest anything, I would crawl into the Marmot bag completely instead of using as a top quilt in this case. I know you'll get very little bonus from the compressed down but it might get you through.

I have slept in 0 degrees with a 20 degree bag, my thermals, and my down jacket. I used a windshield reflector (like the double bubble) and a wool blanket underneath me. It wasn't warm and frankly sucked but I didn't die, nothing froze. I just had a poor nights sleep and learned the limits of some gear.

Ha! I guessed as much. Appreciate the response.

I have been experimenting with insulbrite from Joanns. Its perforated mylar with some fuzzy polyester on each side. I have been bringing a chunk a bit bigger than my tookus with pretty good results. I have used it with my 20 HG down close to ten dungrees frankenstien with not a single problem. It really is a great add on. Breathes really well with all the needle holes too.

Thank you for that insul-bright fabric idea. I might have to buy some to play with various projects!

My advice is to get out in the back yard before the trip and test it in conditions as close to what you will expect. There's nothing more miserable to me than backpacking in, getting cold, and getting no sleep because of the cold only to have to pack back out already tired.
