I'm in the market for a good TQ that I can use all year. Does anything think it would be possible to use a winter quilt (such as the Old Rag Mountain or Black Mamba) in the summer? Or even a 3 season TQ and just supplement from that in the winter? The average temps for winter usually range from 20-30 here. I was thinking of the JRB Hudson River as well. Thanks for any help!
