A cozy sleeping bag is crucial for a good night’s sleep while camping no matter what season it is. The warmer months usually call for a lighter sleeping bag whereas the winter months call for something with more insulation.

When it’s cold, you want to choose the best winter camping sleeping bag that will be suitable for the types of trips you’re planning to embark on. Think carefully about the temperatures you will be camping in as well as the conditions of the environment. Both of these factors will play a role in your decision, especially when it comes to choosing between a down insulated or synthetic insulated sleeping bag.

Sleeping Bags – What to Look for

When searching for a new sleeping bag, one of the most important details to be aware of is the lowest temperature that the sleeping bag is intended for. This number is crucial for winter camping because if you don’t choose the sleeping bag with the proper temperature rating, you could end up in a dangerous situation. Note that this is a guideline and not a guarantee. It is also important to note that the lowest temperature rating often assumes that the sleeper is wearing a set of base layers.

For those camping fanatics who can’t get enough of sleeping under the stars, or those camping out on snowfields at the base of mountains to avoid the bustle of ski resorts, winter sleeping bags are the key to an enjoyable winter camping experience. Below are the 6 best winter sleeping bags we carry, to ensure you’ll be cozy as if in a cocoon on a snowy evening.
