Another shameless plug for Pak-Meister products.
I just got back from a week in the Black Hills. Night time temps were in the low to mid 40s F. I was using my new Jungle Bag which is rated to 40F comfortable. I did bring my fleece liner along as other bags I've had are usually some what less comfortable than their ratings.
Well the Jungle Bag was very comfortable and roomy enough for my 6'1", 225 pound frame. Never took out my fleece liner as there was no need for it. Could have saved the space in the bags!
I like that sleeping bag so much and it's so compact I just ordered 2 more to put in the Bug Out Bags (BOBs) we carry in our cars here. I also added the Emergency Bivi to include in them. Such a small bag is perfect for this purpose.
