No, but I'm getting one. I hate mummy bags
I have the Zenbivy setup in both 10deg. and 25 degree quilts with the fast foot box. I’m using the standard sheet with 25 degree hood. Using a 25x77 thermarest NeoAir pad. I don’t mind carrying a little extra weight for comfort. I’ve mainly used the 25 degree setup. I stayed plenty warm down to 32 degrees in the Sawtooths on a backpack trip. I havnt given the 10 degree quilt a real test yet. I really like the Zenbivy system so far. No mummy bags for me anymore
