How to choose the right one

Check temperature ratings

Match the temperature rating to your expected conditions. The Wayback 20°F offers protection in colder weather, while the Supernova 40°F suits mild nights. The Galactic 30°F sits between them. Select a bag that exceeds your lowest anticipated temperature to ensure comfort. Higher ratings provide more warmth but may add weight or bulk. Always verify the specific rating listed in the specs rather than assuming general performance.

Select shape for space

Shape determines how much room you have inside. Mummy bags like the Cosmic 20 Down taper at the feet to save space and retain heat. Rectangular options, such as the Wayback 20°F, provide uniform width for side sleepers. The Supernova 40°F offers a semi-rectangular fit for versatility. Choose based on whether you prioritize compact packing or unrestricted movement during sleep.

Compare insulation materials

Insulation type affects warmth and packability. Down insulation, found in the Cosmic 20 Down and Galactic 30F, offers high warmth-to-weight ratios. It compresses well for backpacking. Synthetic fills, like the canvas in the Wayback 20°F, are heavier but retain heat when damp. The Supernova 40°F uses down for lighter trips. Decide if you need water resistance or maximum compressibility for your specific gear load.

Verify weight limits

Weight impacts your pack comfort on long trails. The Supernova 40°F weighs just 2 pounds, making it ideal for ultralight backpackers. The Galactic 30F is slightly heavier at 2.7 pounds. The Wayback 20°F weighs 6 pounds, which is manageable for car camping but burdensome for hiking. Check the weight spec to ensure it aligns with your carrying capacity and trip duration.

Measure dimensions carefully

Dimensions determine fit and compatibility with your pad. The Cosmic 20 Down is 30 inches wide, while the Wayback 20°F is 36 inches wide. Lengths vary from 75 to 84 inches. Ensure the bag accommodates your height and preferred sleeping position. Wider bags offer more comfort but may not fit standard sleeping pads. Compare width and length specs to avoid a cramped or oversized fit.
