I just used a Western Mountaineering Sequoia for sleeping in the 4Runner in Utah, and it was nice. Oh, and it is made in the USA.
I bought the cheaper model as I use it to cover a pet carrier in cold weather,so the lining was not important.I would select the other model if you are not going to use a comfortable lining of some type.I have not seen the better model so I can't comment on that lining,but I would not want to sleep on the cheaper model's lining.I do want to say this bag is huge,I will never get it back into the way to small stuff sack,I will try to find a huge duffel somewhere.Did I mention is is huge and difficult to manage?Thoughts between the Teton Mammoth and the Teton Fahrenheit Mammoth, from my understanding is the liner. Difference being one is a brushed flannel versus the 100% cotton flannel.Anyone seen the difference between the two models or have experience with them? Also the pictures show that it compresses down fairly small, but some reviews say they are bulky and huge?
Leaning towards the Teton Fahrenheit Mammoth for winter camping in our RTT.
