Exped's Synmat Duo is the ultimate in outdoor double beds. It offers stellar warmth and comfort in the backcountry and works well for couples who love camping and hate the idea of carrying and using 2 separate sleeping pads. Each half of the Synmat Duo is separately inflated and deflated, which not only gives each user the perfect amount of firmness desired, but also helps in case there's a leak. To prevent the nasty mold that usually forms inside sleeping pads, Exped provides a handy pumpbag that keeps the interior of your sleeping pad moisture-free. If you and your partner are seeking the ultimate in comfort for your backcountry adventures, the Synmat Duo is a fantastic choice.
