I have been searching both the internet and brick and motor stores for a warm weather sleeping bag to use in my tent at the beach and up in the mountains in CA. With so many different ones to choose from, I am wondering what do you guys use? It needs to be kind of long, because I am 6'1". I saw a Coleman multi-weather bag at Sport Chalet, which caught my eye that has removable liners for colder weather and is rated for 20 - 70 degrees, which would be nice for camping in my pop up trailer in the desert in the winter, so I won't need to get a second bag. Any one have any input on the Coleman multi-weather bag?
