How to Choose Between Sleeping Bags

Three and four-season sleeping bags come in two varieties: down insulated and synthetic insulated. Each insulation offers a distinct set of advantages and disadvantages, so it’s important to do some research before you pick your sleeping bag. Temperatures, weather, and sleeping style are all considerations when making your choice.

Down
Down is the lightest, warmest, and most packable form of insulation. However, down loses some of its insulating properties when wet and tends to be more expensive than synthetic insulation. Shop Down Sleeping Bags

Synthetic
Synthetic insulation can better handle wet conditions and usually has a lower price tag than down, but it's also bulkier and heavier. Take this into consideration when planning long trips. Shop Synthetic Sleeping Bags
