David has been in the outdoors business for the past 16 years and is highly experienced in all things camping. He enjoys sharing his knowledge with customers to ensure they have the best camping experience possible.
What should you look for and avoid when buying a sleeping bag?
What features to look out for all depends on what you want from a sleeping bag, says David. “Pay attention to temperature and season ratings. One-two season sleeping bags are suitable for warm summer nights, while a four season will keep you warm in the winter months.”
He also recommends looking for sleeping bags with a “mummy”-like design. “These ones cocoon your head and feet to trap heat,” he says, “but they also don’t provide much room for movement, so if you’re a fidgety sleeper, you may feel restricted, but they do offer more warmth and a smaller pack size.”
For couples, David suggests a double sleeping bag such as the Vango Homestead. “They usually have a zip on each side, so you don’t disturb the other person when getting in and out,” he says.
What are the best sleeping bags for winter, and which are best suited to warmer weather?
According to David, “three-four and four season sleeping bags are the best for winter while one-two and two season are lightweight and ideal for summer nights”. He says that a good option for autumn and milder winter nights is the Vango Nitestar Alpha 350, while the Vango Nitestar 250 is well suited to summer camping.
“It's also worth bearing in mind that some people are warm sleepers and some cold,” says David. “If you're someone that feels the cold, then perhaps it is better to go for warmer. Everyone is different - so it is often hard to measure. Use the temperature gradings as a rough indication.”
How to wash a sleeping bag
Before washing your sleeping bag, it’s worth checking the care label on the bag for specific instructions on the best method to wash. In general, David recommends washing most sleeping bags at 40 degrees Celsius, using normal detergent, and avoiding using fabric softener and tumble drying.
Which is better: down or synthetic filling?
Sleeping bags are filled with either synthetic insulation, down insulation, or a combination of the two. While they both serve the same general purpose, there are advantages and disadvantages to both.
Down-filled sleeping bags
Down is a natural thermal insulator found beneath the feathers of birds. Manufacturers of outdoor products use goose (and sometimes duck) down to fill their sleeping bags. Down fillings are more compact than synthetic fillings when packed down and retain their shape better over long periods.
Down is also more lightweight and has a better warmth-to-weight ratio than synthetic sleeping bags, making it a popular choice among backpackers. The main drawback of down-filled sleeping bags is that they lose some of their insulating properties when they get wet, which limits their suitability in wet or snowy conditions.
Some sleeping bags are filled with hydrophobic down (regular down that has been coated with a water-repellent chemical) to combat this, but some manufacturers claim that this loses some of the down’s insulating properties as a result.
Synthetic sleeping bags
Synthetic sleeping bags, on the other hand, are filled with polyester fibres, which are quick-drying and retain less moisture than down-filled sleeping bags, making them a popular choice for wet and snowy weather.
While synthetic sleeping bags are cheaper than down sleeping bags, their main drawback is that synthetic filling is not as compact as down. They also have a worse warmth-to-weight ratio and lose their shape more quickly after repeated use.
