Whether you're planning a backpacking excursion or camping under the stars in your backyard, a summer sleeping bag will ensure that you stay comfortable during the warmest nights of the year. Although many sleeping bags are lightweight, the best summer sleeping bags are also notable for having a temperature rating of 30 degrees Fahrenheit or warmer, ensuring you won't get overheated.
When shopping around, there are a few key factors to note:
- Temperature rating: To tell the difference between summer, three-season, or winter sleeping bag, look for the product's comfort level temperature rating. This is a standardized figure which represents the lowest temperature (or range of temperatures) you can expect to be able to use the sleeping bag at and still be comfortable. A summer season one typically has a rating of at least at least 30 degrees Fahrenheit, though if your destination sees much warmer weather at night, you may want to look for one with an even higher range.
- Shape: Among the two most common styles of sleeping bags, rectangular (or envelope) is typically best suited for summer because there's more breathing room — your legs can splay out or you can unzip it half or full-way to let more cool air in. On the flip side, a "mummy"-style bag is more restrictive as it zips up all the way up and around you. This style is often preferred for cooler temps because it allows you to retain heat better, however, don't rule it out entirely if you're looking for the most compact (and often most lightweight) option
- Size and weight: Most sleeping bags are a standard 75 inches (or 6.25 feet) long, so anyone over 6-feet tall will want to look for one that's better suited for them. Likewise, if you're planning to backpack or carry your gear for long distances, weight will be also be an important factor. Most of the bags below weigh 2 pounds or less, so they won't add too much weight to your load.
