Family vacations often double as mini camping expeditions for you and your loved ones, so make sure that everyone is well-equipped for the next adventure. Rectangular sleeping bags are roomier and less restrictive than those that are more formfitting, making them perfect for low-maintenance excursions. If you end up needing extra space or are sharing with someone, simply zip a second bag to the first one. Be on the lookout for sleeping bags with a foot box, which will help you stay warm while you sleep and are especially useful for those who sleep on their backs. When shopping around for men's sleeping bags and women's sleeping bags, keep in mind how often you plan to use it and under what circumstances to ensure the best possible fit for you.
