Sleeping Bag Tips for Condensation

Happy campers wake up warm and dry in the morning. But these pleasant conditions are difficult to find when your sleeping bag is coated in condensation. She can surprise even experienced campers that condensation is likely to come from their own bodies and is wicking through the bag during the night. Follow these strategies to reduce or eliminate condensation in your sleeping bag.

How To Form Condensation On A Sleeping Bag

Condensation is a result of humidity and temperature. Moisture is simply the air humidity at night, some insulation, waterproof sleeping bag traps warm air given out by your body. The material of the bag is designed to breathe without leaving moisture. What happens is that your body gives off moisture from the air inside the bounds of the sleeping bag. The air escapes through the insulation and runs to the waterproof shell where it meets colder temperatures, causing the water to condense on the surface of the bag. If you issue an unusual amount of body heat you can find also condensation formed inside the bag, leaving it wet and uncomfortable.

Choose Your Campground Wisely

Outdoor camping not where the air circulates more freely. Even raising a tent under a grove of trees can help reduce the formation of condensation.

Unless you’re camping in sub-zero conditions, consider leaving the sleeping bag partially unpacked so that your body heat can evaporate without going through the bag and condensation on the surface.

Create your tent for ventilation. The inside of a wall tent is a paradise for condensation, and your tent could turn into a forest on a cold night. Even with the cold weather, the heat of the body and breath of 3-4 people in a tent is enough to absorb all sleeping bag unless there is some ventilation to circulate air. Avoid breathing inside the sleeping bag, because this only encourages the formation of condensation.

Bivys, Sleeping Bag Covers And Tarps

Bivys are a type of vapor barrier that fits inside your sleeping bag to keep moisture from the body heat from seeping into the insulation during the cool weather and cold. These tend to be a more expensive solution to problems once the condensation of Bivouac is molded to fit specific types of sleeping bags.

As a low-cost alternative, a waterproof sleeping bag cover or canvas on the outside of the sleeping bag creates a layer of trapped air that acts as additional insulation. If the cold air can’t get to your bag, it’s less likely chance of colliding with the moisture from your body heat to produce condensation.
