My wife and I walked the Arizona Trail in 2012. Biggest drawback was the lack of good night's sleep and cuddling time in our Big Agnes mummy bags, even when zipped together. Too hot, too cold, too enclosed, and the pads kept slipping apart. This new Dreamwalker Duo is perfect for our need for versatility on the long treks. Weight was a big consideration for us as well. The only other sleep systems available for couples like us were well outside our price range. We're looking forward to the Colorado Trail and the Pacific Crest.
