For backpacking in cold weather, a synthetic or down mummy bag provides better warmth-to-weight ratio.

HiZYNICE HiZYNICE Sleeping Bags for Adults XXL Cold Weather

HiZYNICE Sleeping Bags for Adults XXL Cold Weather

Brand: HiZYNICE

Best for

Larger adults who need extra width and length in a cold weather sleeping bag, where standard-size sleeping bags do not provide enough room for taller or wider adults to sleep comfortably and the XXL HiZYNICE provides the additional dimensions needed for a full range of sleeping positions without the bag constricting shoulder movement.

Skip if

Standard adult sizing is sufficient. XXL sleeping bags are wider and longer than necessary for most adults, which adds weight and bulk without benefit.

Questions people ask

What temperature rating do I need for winter camping?

For winter camping, a sleeping bag rated at 0 to 15 degrees Fahrenheit covers most cold-season camping in the continental United States at standard campground elevations below 5000 feet. Mountain camping above 6000 feet and far-northern locations may require minus 10 to minus 20-degree rated bags during the coldest months. The EN or ISO temperature rating system provides three numbers: comfort, lower limit and extreme. The lower limit rating is generally what manufacturers advertise; the comfort rating is approximately 5 to 10 degrees warmer than the lower limit and is the temperature at which an average sleeper is comfortable rather than merely safe. Use the comfort rating rather than the lower limit for a realistic assessment of when the bag will keep you warm.

Is a cotton sleeping bag better for winter camping?

Cotton sleeping bags are warmer-feeling against the skin than synthetic sleeping bags for car camping because cotton flannel holds heat generated by the body and provides a soft surface contact. For car camping where the sleeping bag stays dry and is not carried in a hiking pack, cotton flannel cold weather bags are a comfortable choice. The significant limitation of cotton for camping use is that cotton absorbs moisture and dries slowly; a wet cotton sleeping bag loses most of its insulating value and takes many hours to dry, which creates a hypothermia risk in sustained wet conditions. Synthetic fill sleeping bags dry faster than cotton and retain some insulating value when damp, making synthetic the safer choice for camping in wet climates or when the bag might get rained on during setup.

How do you stay warm in a sleeping bag when camping in winter?

Layer clothing under the sleeping bag rather than sleeping in minimal clothes inside a sleeping bag; a moisture-wicking base layer and lightweight thermal layer add warmth inside any bag. A sleeping bag liner adds 5 to 15 degrees of warmth inside an existing sleeping bag at low cost and weight. Place a foam sleeping pad or air pad under the sleeping bag; heat loss through the ground is significant because the compressed sleeping bag underneath the sleeper provides almost no insulation. Eating a light snack before sleeping provides the body with calories to burn for heat generation during the night. Breathe outside the sleeping bag rather than inside; breathing inside adds moisture to the bag interior that eventually reduces its insulating capacity.

    Best mummy sleeping bag: lightweight tapered camping picks on Amazon

    A mummy sleeping bag tapers from the shoulders to the feet, following the body shape to minimize the interior air volume the body must heat. The narrower profile makes mummy bags lighter and more thermally efficient than rectangular bags at the same temperature rating.
