Sleeping Bag Blog

Standard sleeping bags are fine for slumber parties and other indoor use. They are also adequate for warm summer nights under the stars. Serious campers and hikers will want to look beyond this regular sleeping bag design, however. Only a well-insulated bag with better heat-retention properties will suffice for these hardened outdoors enthusiasts.

Mummy bags, such as Slumberjack sleeping bags, are more than mere blankets with zippers attached. Named for their tapered shape—which recalls ancient Egyptian burial chambers—these bags stand up to cold weather due to their advanced insulation properties. For instance, mummy bags feature a drawstring that helps to prevent heat loss. Mummy bags also tend to be more restrictive, especially around the feet. This decreases the sleeping bag’s overall volume and allows the bag to better retain your body heat.
