Different Types of 20 Degree Sleeping Bags

Searching for a perfect sleeping bag to keep you snug and warm on your adventures can seem easy with all those options on the market- but while there are so many varying designs to choose from, this also means you’ll have to consider different factors to ensure you’re getting the proper fit for your needs.

When it comes to the type of sleeping bags, it’s their shape that determines it. The “mummy” design is one of the finest solutions for cold weather camping. This construction boasts a shape that is tapered, clinging to your body, protecting your head, and offering superior protection for your limbs and face. This last factor is crucial – hands and feet, as well as your head, can remain exposed and freeze, so a sleeping bag with a snug fit is a great choice.

The “envelope” design is a real classic when sleeping bags are considered. A basic, reliable rectangle shape and great insulation properties are a great solution for some casual sleeping when you are out backpacking or camping. One of the main advantages here is its flexibility and the option to fold it quite compactly – making it easy to carry around. Also, most envelope designs can be fully unzipped, giving you the option to use it as a great mat or even a big blanket – perfect for some camping trips, especially in combination with other equipment such as a sleeping pad.

Last but not least is the double sleeping bag design. Serving more as an outdoors “bed”, this type of sleeping bag is aimed at couples who adventure together. And we all know that sleeping huddled close to your companion can double the heat in winter, so it’s a win-win situation. The double sleeping bag design has a widened shape that allows two to comfortably share the space or a plus-size sleeper to sprawl freely.

In addition to the type of sleeping bag, you should also make sure that the 20-degree sleeping bag you’ve picked out is water-resistant or waterproof (DWR coating can greatly help with this), and made from durable materials that prevent the heat from dissipating, such as synthetic fabrics and fills, as well as naturally insulative materials such as down. Furthermore, if you want to cover all your bases, pick designs that have special cold weather-friendly features such as a draft collar or a draft tube.
