Best Lightweight Sleeping Bag for Backpacking

Your sleeping bag is one of the most important – and one of the bulkiest – items you’ll need with you on a backpacking trip. This means you need to pay careful attention to the weight of your bag when making your choice.

Of course, you also need to be sure the bag is warm enough, which can add weight. The good news is the average sleeping bag has enough insulation to keep you comfortable in most climates so that you can focus more on the weight you’ll be carrying as opposed to the filling when shopping for a lightweight sleeping bag.

Weight and Insulation

When making decisions about a sleeping bag’s warmth, make sure to use the 20-degree rule of comfort. This means that if a sleeping bag says you’ll survive the night at a certain temperature, this doesn’t mean you’ll be comfortable sleeping in that temperature. To determine the comfort rating based on the survival number you’re given, add about 20 degrees. For instance, if a sleeping bag is listed as suitable in temps as low as 10 degrees, you’ll probably be comfortable in it with no additional layers at about 30 degrees.

Though five pounds might not seem like a lot when you’re shopping for a sleeping bag, when you’re carrying it along on your hike with everything else you need to bring with you, the difference between two or three pounds and five pounds can be significant. The key to getting the right bag is to choose the lightest weight possible within your budget and within the level of warmth you need based on your usual hiking destinations.

Other considerations you’ll want to factor in when choosing a lightweight sleeping bag include:

  • Compressibility. The warmer the bag, the bulkier it will be. Some bags offer straps and ties to make compression easier. Compression doesn’t necessarily affect weight, but it does affect the efficiency of packing and how much you can carry with you in total.
  • Interior space. Some of the lightest weight sleeping bags tend to be narrow, which might not be comfortable for sleepers. Tighter bags are also warmer, so some manufacturers create more form-fitting bags to reduce the amount of insulation needed. The interior size of your bag is a personal preference, but it’s something to consider when shopping.
  • Entry and exit ability. If possible, opt for a zipper-free sleeping bag. If you prefer a bag with a zipper, stay away from heavier metal zippers. Nylon and plastic zippers tend to be lighter weight and are more durable.
  • Type of insulation. Do you prefer a down or synthetic fill? Down is lighter and warmer, but not everyone wants a bag filled with down feathers. Synthetic might be more cumbersome and not as warm, but it performs better if it gets wet and bags filled with synthetic materials tend to be cheaper.
  • Style. Do you prefer a mummy or quilt style bag? Mummy bags offer head coverage and therefore tend to be warmer, but they are too constricting for some sleepers.
  • Pad loops and pockets. If you are traveling with a sleeping pad, does the bag offer a way to fasten the pad into place? Both pockets and loops for attaching your pad tend to add weight, but might be worth it if it makes for a secure evening of sleep.
