Double Sleeping Bags Buying Guide

There are plenty of great double sleeping bags out there, so it’s critical that you know what to look for before you buy.

Here are 6 key features of double sleeping bags to consider as you shop.

Temperature rating

The temperature rating of a sleeping bag denotes the lowest temperature that a specific model can be used at. This gives you an idea of which season is most appropriate for camping with a given sleeping bag.

Here are some general temperature rating ranges to know:

  • +15ºF or Lower. Models rated to under 15ºF (-9ºC), like the Big Agnes Dream Island 15, are best for wintertime use.
  • +15ºF to + 30ºF. Sleeping bags designed for 15º to 30ºF (-9º to -1ºC), such as the Exped MegaSleep Duo 25, can work well for summer, spring, or fall use in chilly areas, but are generally too warm for mid-summer.
  • +30ºF and Higher. Any sleeping bag rated above 30ºF, including the Klymit KSB Double Sleeping Bag, is crafted for summertime use in warm environments.

However, keep in mind that a sleeping bag temperature of, for example, 20ºF rating doesn’t mean you’ll be very comfortable in that bag at 20ºF. Instead, you’ll be just barely warm enough to get through the night.

So, it’s best to get a model that’s rated to 10º to 15ºF (5º to 8ºC) warmer than the lowest temperature you expect on your trip.

Type of insulation

Sleeping bag insulation has a direct impact on the performance of your sleep system in the real world. There are two types of insulation; down and synthetic.

Down insulation

Down insulation, such as what’s found in the Big Agnes Sentinel 30, is often considered the gold standard in outdoor gears because it offers excellent warmth to weight ratio. That means a down sleeping bag can offer much more insulation than a synthetic model of the same weight.

When it comes to down insulation, quality is measured in terms of fill power. Fill power simply is a measure of how much loft down has, with a higher fill (e.g. 900) providing more warmth per gram than a lower fill (e.g. 650).

Down with a higher fill is warmer per gram, so manufacturers can create a lighter sleeping bag that’s very warm when using a high fill down.

Of course, this comes with a higher price tag but is worth it if weight savings are your top priority.

The downside to down insulation is that it is not effective at keeping you warm when wet. While some models, like the Therm-a-Rest Vela Double 20, have down that’s treated to be water-resistant, if the bag gets completely soaked, it won’t keep you warm.

Synthetic insulation

Synthetic insulation, such as what’s found in The North Face Eco Trail Bed Double 20, is a budget-friendly alternative to down. Although synthetic is bulkier and heavier than down of the same volume, it is more effective at keeping you warm when wet.

Most synthetic insulation is made from polyester fibers.

Some synthetic technologies, like the FireLine Max synthetic insulation found in the Big Agnes Dream Island 15, combine different types of fibers to create a better warmth-to-weight ratio without a drastic increase in price.

Size and dimension

Interestingly, double sleeping bags are often larger than two single sleeping bags put together. This is because they offer a bit more wiggle room for two people to sleep comfortably without feeling claustrophobic

Most double sleeping bags are at least 70” wide and 70” long, which is enough space to fit two people that are under 5’8” tall.

However, some models, like the Therm-a-Rest Vela Double 20 are 80” long, which is perfect for campers that are up to 6’ 6”.

Additionally, some bags, like the NEMO Tango Duo Sleeping Bag, are 80” wide for extra wiggle room and personal space as you sleep.

While having a larger sleeping bag might seem ideal from a personal space standpoint, keep in mind that larger bags often weigh more. You’ll also want to compare the size of your double sleeping bag with the interior size of your tent, as you may need a 3 person tent to accommodate a sleep system of this size.

Outer shell materials

Sleeping bags are designed with two standard types of outer shell materials, namely nylon, and polyester.

This is how they perform on a camping trip.

  • Ripstop nylon. Ripstop nylon shell fabrics, such as those found on the NEMO Tango Duo Sleeping Bag, are strong, durable, lightweight, and highly packable. As you can imagine, such a great combination of features often comes at a high price.
  • Ripstop polyester. Polyester is a commonly used shell fabric on budget-friendly double sleeping bags where cost is the main priority. As a fabric, ripstop polyester is durable, but it is bulky and heavy when compared to nylon.

In addition to these shell fabrics, many companies apply a DWR coating to the outside of their sleeping bags. DWR, or durable water repellent, helps to prevent water from seeping through the fabric so it won’t affect the warmth of your sleeping bag.

However, with the exception of some sleeping bags designed for extreme winter conditions (e.g., -20ºF/-28ºC or under), you generally won’t find sleeping bags that have fully waterproof shells. This type of shell is great if you’re going to sleep directly on the snow, but it’s too bulky, heavy, and expensive for most camping trips.

Packed size and weight

The vast majority of double sleeping bags will weigh more than a single sleeping bag made from the same materials and rated to the same temperature because double sleeping bags are inherently larger.

For the most part, double sleeping bags are between 4 to 8lbs (1.8 to 3.6kg) in weight, with winter bags almost always being heavier than those designed for summer use.

Additionally, down double sleeping bags, like the NEMO Tango Duo Sleeping Bag, are almost always going to be lighter than synthetic alternatives with the same temperature rating.

This is because down has a better warmth-to-weight ratio, so less down can be used to achieve the same amount of warmth as synthetic fill.

Extra features

For added functionality, many sleeping bags come with extra features that provide warmth and comfort while outside.

These are some of the most common options you can look out for :

  • Hoods. While hoods are very common on single sleeping bags, they’re less common on double bags. That being said, hoods, such as those found on the Klymit KSB Double Sleeping Bag, are ideal if you’re camping in cold conditions as our heads can get very chilly in the night.
  • Stash pockets. Stash pockets, such as those in The North Face Eco Trail Bed Double 20, are small gear storage areas inside a sleeping bag where you can place a phone, headlamp, or earplugs for easy access throughout the night.
  • Draft tubes. Draft tubes are found on some sleeping bags like the Exped MegaSleep Duo 2. They are basically long tubes of insulation that are placed around a bag’s zipper. These add a slight amount of weight to your pack but are great at blocking out cold air that often sneaks through your zipper at night.


Should I get a single or double sleeping bag?

If you want to cut down on weight and cost, but don’t mind cuddling with your tent mate, then a double sleeping bag is a sure bet. Otherwise, single sleeping bags provide more personal space while camping.

Is a 3-season sleeping bag warm enough in the winter?

3-season sleeping bags are not warm enough for winter use in cold places like Denali National Park or Rocky Mountain National Park. However, in places with warm winters, like Everglades National Park, 3-season bags are sufficient.

Can you zip two sleeping bags together?

So long as two sleeping bags have zippers of the same size, you can often zip them together. Some models are actually built to be zipped together, however, this is often the heavier option when compared to a double sleeping bag.
