How to Choose a Backpacking Sleeping Bag
Picking out a new backpacking sleeping bag for any outdoor adventure can be super overwhelming. There are so many choices and so many features to consider, not to mention the price tag. We’ve put together a simple guide that breaks down how to choose a backpacking sleeping bag for your next great adventure.
••• Sleeping Bag Temperature Rating •••
The sleeping bag temperature rating is the first place to start when picking out a new backpacking sleeping bag. Think about when and where you plan to use it the most.
Sleeping bags can be broken down into three simple categories: summer, 3-season, and winter based on the temperature ratings shown in the table below.
Most people will be happy with a 3-season bag, which will keep you comfortable most of the year. Remember you can always zip down the bag for a summer camping trip or add a liner to your bag for an occasional winter camping trip!
Most 3-season backpacking bags will list an EN testing rating with two temperature ratings known as the “comfort rating” and the “lower-limit rating”. Comfort rating is the lowest temperature at which the bag will keep the average woman or “cold sleeper” comfortable. Lower-limit rating is the lowest temperature at which the bag will keep a man or “warm sleeper” comfortable. (EN ratings are based on a sleeper wearing one long underwear layer and a hat, and sleeping on a single one-inch thick insulating pad.)
••• Sleeping Bag Shape •••
While the sleeping bag shape might not seem important, it is for two big reasons:
To Quilt or Not to Quilt?
Some lightweight backpackers won’t even entertain the idea of a sleeping bag as they are all about the “camping quilt”. We’ll include one recommendation for a great quilt if you are interested in going ultralight.
••• Synthetic vs Down Sleeping Bag Insulation •••
Synthetic Backpacking Sleeping Bags
Synthetic bags are often made with polyester, they are quick-drying, and can insulate even when wet. They are much cheaper and non-allergenic. What’s the downside? Synthetic bags don’t compress as small as down sleeping bags, and synthetic tends to be heavier.
Down Backpacking Sleeping Bags
The biggest advantage of down vs synthetic is down bags tend to be lighter and compress smaller when packed away – key characteristics when you are using the bag for backpacking. Most say down is more durable than synthetic as well. Generally down is more expensive than synthetic and it doesn’t insulate as well when it is wet. However, many down sleeping bags are now coated with a water-repellent finish that will keep you warm and dry in damp conditions.
Synthetic is also a good option for those of you who choose to live a vegan lifestyle, as down is produced from geese or ducks.
••• Other Important Backpacking Sleeping Bag Features •••
Sleeping Bag Hood
Vital for sleeping in cold temperature as we lose heat through our head, it’s essential to have a hood on your bag to keep you warm. Most mummy bags and semi-rectangular bags come with a hood.
Some bags come with pillow pockets to put stash your clothes to create a pillow while others come with stash pockets to keep your glasses, a watch or cell phone nearby. Some bags also come with sleeping pad pockets or a sleeping pad sleeve to fit a sleeping pad so you don’t roll off the pad in the middle of the night. These pockets are personal preference, and the extra fabric might add to the total weight of the bag.
Double Sleeping Bags
Backpacking with your significant other? Several companies are now making double sleeping bags so you can cuddle why you’re camping.
••• The Best Backpacking Sleeping Bags •••
When you backpack, you’ll see lots of people with the same sleeping pads, same tents and same water filters, but when it comes to sleeping bags rarely do you find an outlier that is most recommended or most popular. Below are our personal favorites for the best backpacking sleeping bags.
Best Sleeping Bag Buy
Kristen used this REI Joule (Women’s) sleep bag on her John Muir Trail hike. For a 23 degree bag it is one of the lightest out there for the price. Kim also used this same exact bag for her 2016 hike of the Pacific Crest Trail and ran into numerous other thru-hikers with the exact same bag. Her dad used the male model of the bag when he joined her for 9 days and was very pleased with the bag– Igneo (Men’s) Sleeping Bag.
Best Warmth to Weight Ratio
Western Mountaineering arguably make the best sleeping bags out there. They have 30 degree down, 20 degree down and 10 degree down bags that are some of the lightest for their weight class. Kristen has the Western Mountaineering Versalite 10 degree bag, which weighs a mere 2 pounds, and it’s 10 degrees warmer and a few ounces lighter than Joule. Western Mountaineering sleeping bags come in 3 different lengths and you can choose whether you want it to zip on the right or left side. Be prepared though, these come with hefty price tags.
Best Sleeping Quilt
Weighing in at only 1lb, 6oz, we can’t argue against the excellent Therm-a-Rest Corus HD Quilt Sleeping Quilt. It’s a 35 degree quilt, however, so it’s better for warmer climates. The footbox is rounded with elastic, forming a nice pocket for your feet, and the quilt comes with snaps that allow you to attach it to your sleeping pad.
Best Synthetic Summer Bag (And CHEAPEST OVERALL)
Mountain Hardwear’s Lamina Z Spark Sleeping Bag is the best synthetic bag for the price and weight. It’s EN comfort rating is 42 degrees, but at 2 lbs 1 oz and a low price tag of $160, this is one of the best sleeping bags for beginner backpackers who tend to camp in summer or warmer climates and don’t want to throw down a ton of cash.
Best Double Sleeping Bag
Want to snuggle with your honey? Many companies are now making double sleeping bags. In the past, double sleeping bags were heavy and cumbersome to pack up. Not so much now. This NEMO Tango Duo Sleeping Bag is rated for 30 degrees and only weighs 2 lbs 9 oz. When you consider that that’s only 1 lb 4.5 oz per person, you actually save weight when compared to carrying 2 separate sleeping bags.
