What’s better than nights under the stars, days on the trail, and summiting mountains to well-earned vistas? Experiencing the trail, mountains, and nature with someone using the best 2 person sleeping bag! 

Getting outdoors can do wonders for the introverted soul and contemplative loner, but adventuring can, and often should, be shared as well, and just because the sun goes down doesn’t mean you and your partner have to go separate ways. 

In fact, the folks over at Sierra Designs are doing everything in their power to make sure you don’t, just look at the Sierra Designs Backcountry Bed Duo for all the proof you need.

Best 2 person sleeping bag

The most obvious benefit of the Sierra Designs Backcountry Bed Duo is that it was designed, manufactured, and spec’d to comfortably accommodate two adventurers to sleep side by side with ease whether you’re in the high sierra’s or deep in the forests of Appalachia.

Depending on the build you buy, the bag easily accommodates hikers up to 6’6” tall and can even accommodate the addition of each hiker’s sleeping pads to maximize comfort. This sleeping bag doesn’t just try to squeeze two campers together and call it done, instead it goes the extra mile to insure you and your partner get to experience the wilderness together with every ounce of comfort a campsite can offer.

Backcountry in Mind

Of course, you can’t just market any item as being friendly for backcountry camping and then design it to weigh half a ton. Backcountry usually implies we’re going to be doing a fair amount of trekking away from easily accessible paths and comforts to reach our campsite. As such, staying light and convenient is a must for every item of gear you carry.

The Sierra Designs Backcountry Bed Duo, while heavier than a normal one person sleeping bag, is still a very reasonable haul assuming you’re hiking with a partner who is sharing the load. The bag stuffs down tight and weighs in at just over 4lbs. Ideally, you want to stow the tent on one person, the bag on the other, and you’re left with a shared weight ratio and a great night’s sleep ahead.

Designed Like Home

One of the coolest things about the Sierra Designs Backcountry Bed Duo is its ingenious design. There’s hardly anything like it on this market. The designs mimics the top tongue of a shoe to insure that you get a similar experience sleeping on the trail as you would at home. 

The top comforter is layered under the outer layer of the bag and can be pulled up to your face when it gets chilly or left to linger around your feet when you want to enjoy the summer night air. The bag also featured two options of fills. You also have the option of either a synthetic or down fill to keep you comfortable based on your preference of hiking environments and weather.

What Customers Are Saying

The Sierra Designs Backcountry Bed Duo is obviously one of a kind with its comforter design and spacious accommodation all while staying backpacker friendly. The thing that impresses people the most is the bags ability to keep the hikers cozy but while not leaning too far towards either temperature extreme thanks to great insulation and the foot vent.

Among the positive comments people have made about this bag, some have remarked that 4lbs is a heavy weight for a backpacking sleeping bag. However, it’s important to remember that duo sleeping bags are a unique accommodation to backcountry, and 4lbs is actually pretty light considering what the bag provides for the camping experienceIts sheer unique design and backpacker friendliness is more than enough for me to sincerely recommend this as a great 2 person sleeping bag!

Who Should Buy this Product?

This bag is perfect for the couple in love with each other and adventure. It’s great to take on weekend motorcycle getaways, backcountry excursions, and everything in between. This sleeping bag will best be used and appreciated by those couples who want to spend and savor every moment of the adventure together which includes everything from epic vistas to serene nights under the stars together.

Who Shouldn’t Buy this Product?

This sleeping bag won’t be optimum for the hiker who values pack weight and convenience over intimacy with their hiking partner. It’s understandable that some hikers just want to stay as light as possible, so they won’t see the extra pounds this bag entails as a worthy sacrifice.


The Sierra Designs Backcountry Bed Duo bag is by far the most unique and best 2 person sleeping bag on the market. Its state of the art design, convenience for backpackers, and spacious accommodation means it’s a great back to get you and your partner out the door and into nature together.
