Materials and Insulation

Down Insulation

Its made from the soft feathers of ducks or geese, is known for its excellent warmth-to-weight ratio and compressibility. Down sleeping bags are lightweight and straightforward, making them ideal for backpacking. However, they can lose their insulating properties when wet, so keeping them dry is essential.

Synthetic Insulation

Synthetic insulation, usually made from polyester fibers, retains heat even when wet and dries quickly. Those sleeping bags are often more affordable than down bags and are a good choice for damp or humid conditions. However, they tend to be heavier and less compressible.

Hybrid Options

Some sleeping bags combine down and synthetic insulation to offer the best of both worlds. These hybrid sleeping bags provide excellent warmth, moisture resistance, and packability.

Weight and Packability

Ultralight Options

For backpackers and those who need to minimize weight, ultralight 0-degree sleeping bags are the way to go. These bags use high-quality down or advanced synthetic materials to provide warmth without the bulk.

Standard Weight Bags

Standard-weight 0-degree sleeping bags balance warmth, weight, and cost. They suit various activities, from car camping to moderate backpacking trips.

Key Features to Look For

Hood and Draft Collar

A well-designed hood can significantly increase a sleeping bag’s warmth by trapping heat around your head. Draft collars and tubes along the zippers also help prevent cold air from entering the bag.

Zipper Quality and Placement

Look for sleeping bags with high-quality zippers that operate smoothly without snagging. Some bags offer two-way zippers, which allow you to ventilate the bag from the bottom without exposing your upper body to the cold.

Water Resistance

Many 0-degree sleeping bags feature water-resistant or waterproof shells to protect against moisture. This is especially important for down bags, as down loses its insulating properties when wet.
