How to choose the right sleeping bag

Match temperature ratings

Check the temperature rating to ensure the bag handles your local climate. Both listed models share a 20°F rating, meaning they suit cold nights. If you camp in milder weather, this rating may be excessive. If you expect freezing conditions, verify if the insulation type provides enough warmth. Always align the rating with your expected low temperatures for comfort.

Select shape for space

Choose between rectangular and mummy shapes based on your comfort needs. The Mammoth features a rectangular design with a 62-inch width, allowing you to move freely. This suits couples or those who dislike confinement. The Altos uses a mummy shape with a 33-inch width, which traps heat more efficiently but restricts movement. Pick the shape that fits your sleep style.

Consider weight for travel

Weight determines how easy the bag is to carry. The Altos weighs 2.5 pounds, making it ideal for backpackers who need to minimize load. The Mammoth weighs 14 pounds, which is heavy for long hikes but manageable for car camping. If you drive to your site, the extra weight is irrelevant. If you hike miles, prioritize the lighter option.

Check length for height

Ensure the bag length accommodates your height to avoid cold feet. The Mammoth measures 94 inches long, fitting taller sleepers comfortably. The Altos is 84 inches long, which may require curling for very tall users. Measure your height against these specs before buying. A bag that is too short compromises warmth and comfort significantly during sleep.

Verify insulation material

Insulation type affects warmth and packability. The Altos uses down insulation, which offers high warmth-to-weight ratio and compresses small. This is best for hikers needing efficiency. The Mammoth does not list down, implying synthetic or other fill. Synthetic fills often retain warmth when wet. Choose down for dry, cold conditions and lighter loads, or other types for wet environments.
