- Temperature Rating: Look for a sleeping bag with an appropriate temperature rating for your intended use. This rating indicates the lowest temperature at which the bag will keep you warm, which is crucial for ensuring comfort during cold nights in the wilderness.
- Insulation Type: The insulation can be either synthetic or down, each with its pros and cons. Synthetic insulation tends to dry quickly and insulates even when wet, while down insulation is lighter and more compressible, providing excellent warmth-to-weight ratio but can lose its insulating properties when damp.
- Size and Weight: Since you’ll be carrying your sleeping bag in a backpack, its size and weight are significant considerations. Look for a bag that is lightweight and packs down small, allowing for easy transport without taking up too much space.
- Zip Configuration: Ensure that the sleeping bag has a smooth zipper mechanism and the ability to zip together with another bag. This feature allows for versatile use, such as forming a double sleeping bag for couples or friends sharing space.
- Material and Durability: The outer fabric should be durable and water-resistant to withstand the rigors of outdoor use. Additionally, consider the inner liner material for comfort against your skin and breathability to prevent overheating.

What Size and Weight Are Ideal for Backpacking?
The size of the sleeping bag is also important; zip-together models should be spacious enough to accommodate two people but not so large that they become cumbersome to pack. Typically, a combined length and width that fits the dimensions of two sleeping bodies yet compresses well is ideal for backpackers.
Packability is another key factor, as a good backpacking sleeping bag should compress significantly into a manageable size to save space in your pack. Look for bags that come with compression sacks, allowing you to minimize bulk.
The temperature rating of your sleeping bag is vital for ensuring comfort during cold nights. Opting for a bag that is rated for slightly lower temperatures than you expect to encounter can provide an extra layer of comfort without adding unnecessary weight.
Finally, the shape of the sleeping bag can influence weight and comfort. Mummy-shaped bags tend to offer better heat retention due to their snug fit, while rectangular bags provide more room to move, making them ideal for couples who choose zip-together options.
