SunnySports S Mummy bags are not designed to mate. There shape takes very little body heat to warm them and their insulation is able to hold the heat in keeping the sleeper warm. This is especially true for a bag rated to 20 degrees F. Putting two together would create cold spots and defeat the purpose of the bag.
