Things to Consider When Buying a 0 Degree Sleeping Bag
When sleeping in the great outdoors, sleeping bags will help you get a good night’s sleep despite being far from your comfortable bed. But, if you will be sleeping outdoors in low temperatures, you can’t buy ordinary sleeping bags since they are not made for these climates.
If you will be purchasing one of the best 0 degree sleeping bags in the market for your next trip, here are the things you need to consider:
- Insulation –
Since you will be sleeping outdoors in low temperature, you need a sleeping bag that has an insulated filling to keep you warm. There are two types of insulation fillings that you can pick from: synthetic and goose feather down.
Goose feather down or down fillings are often used for 0 degree sleeping bags because of its insulation properties. They are lighter to bring around as well, making them ideal for camping trips. If you get it wet, the down will still keep you warm and toasty. But, goose feather down is expensive, making it an investment that regular campers or travelers can pick if they will use it regularly. People with allergies should avoid getting these sleeping bags because the down may have allergens that can be bad for their health. People are also advised to do their research about these sleeping bags because each down sleeping bag has different fill power that affects their weight.
Synthetic fillings are made from polyester, which also has great insulation properties like goose feather down. Since polyester is a synthetic material, it is cheaper than goose feather down. It is also hypoallergenic, which is perfect for customers with allergies. Even if it gets wet, the insulation properties of synthetic-filled 0 degree sleeping bags do not change. But, sleeping bags with synthetic fillings can be hard to manage because they don’t fold down easily. They are also heavier than down feathers, which will not be ideal if you will bring them for camping.
- Temperature Rating –
A 0 degree sleeping bag is ideal for people going to winter conditions or areas in higher elevation. But, to know if a sleeping bag can withstand extreme temperatures, you should check if they pass the EN and ISO ratings.
The EN 13537 rating or the European Norm rating is divided into four categories – EN Comfort, EN Lower Limit, EN Limit, and EN Extreme – which differ on how warm a bag should be to guarantee continuous and comfortable sleep for its users. The ISO 23537 rating or the International Organization for Standardization Rating uses the same test used by the EN to rank sleeping bags.
- Shape –
A sleeping bag’s shape, no matter when you will be using it, can play a key role on how comfortable you will be when you are inside it. In this case, the shape of a 0 degree sleeping bag will tell you how long they can retain heat.
A majority of today’s 0 degree sleeping bags have mummy shaped designs which have been known for having great insulation properties. However, it can be very tight for some users and some may even find the shape claustrophobic. There are other designs available for users to check, especially for tall people who need a larger sleeping bag.
Before you purchase a 0 degree sleeping bag, make sure that you try it on before you buy them. You can also do a mock test with them with the help of the shop assistants to see how much space you have when you have the bag zipped over.
- Weight –
When it comes to 0 degree sleeping bags, their weight often gives the idea of how warm it will be when in use. The heavier it is, the warmer it is.
But, while this may be the case, its weight can be a problem if you are bringing it to far expeditions or long trips. It can be a hassle to bring a sleeping bag which may have great insulation, but very bulky to carry around. Consider how long or where you will bring the sleeping bag when considering how heavy it should be.
- Extra Features –
Every sleeping bag in the market considers the comfort of its users when they are using it. They will include features like adjustable hoods, built in pillows and others. For 0 degree sleeping bags, it is ideal if you check features like zipper baffles which can help regulate the heat inside the bag. It must also have anti-snag zippers, which guarantees that cold air won’t seep through the bag and make it easier to move.
- Price –
When buying a 0 degree sleeping bag, consider how long and often you will use them so you know which ones to buy. If you will use it for a long time, invest on one that is both durable and long-lasting.
- Maintenance –
Finally, you have to consider how easy it is to maintain the sleeping bag when it is not in use. As it is regularly washed through washing machines or hand washing, the filling may lose its insulation properties. Experts recommend that after each wash, the bags must be aired out under the sun for a few hours.
If you got a 0 degree sleeping bag made with synthetic fillings, check the maintenance instructions included in the bag. Wrong washing and water temperatures can damage the sleeping bag entirely.
If you bought a 0 degree down sleeping bag, you don’t have to wash it very often. If there are stains, you can clean them with soap and leave it to dry on its own. If you will be machine washing it, use the lowest settings with cold water.
