America’s Best Backpacking and Outdoor Adventures
By Michael Lanza
Finding a sleeping bag that’s right for you may be the most confusing gear-buying task. Getting the right one is critical to sleeping comfortably in the backcountry—and in an emergency, your bag could save your life. But with the myriad choices out there, how do you tell them apart, beyond temperature rating and price? This article will explain how to evaluate the key differences between bags to make your choice much more simple.
Three-Season Sleeping Bag
Marmot Scandium (20° F)
$199, 2 lbs. 14 oz. (regular)
Sizes: regular and long ($219)

A backpacking truth: You can say what you want about the details of a bag’s construction, but the real measure of its value comes on nights when you need it to accomplish just one function—keep you warm. Beside Quiet Lake at over 9,200 feet in Idaho’s White Cloud Mountains in early October, I awoke to find frost coating much of our gear that we’d left outside the tent; the overnight low had dropped nearly to freezing. And I had not even noticed the cold, snoozing comfortably all night in the Scandium.
Three-Season Sleeping Bag
Kelty Dualist 20
$150, 3 lbs. 1 oz. (regular)
Sizes: regular and long ($160)

Outfitting yourself with good-quality backpacking gear when you’re on a budget can be a challenge, especially core gear like your pack, boots, tent, and sleeping bag. That’s why I wanted to test out Kelty’s competitively priced Dualist 20 on a weeklong rafting trip down Idaho’s Middle Fork of the Salmon River, where I discovered this dual-insulation bag delivers a lot of value for its bargain-basement price.
Two-Season Sleeping Bag
Sierra Designs Mobile Mummy 800 (30° F)
$330, 1 lbs. 12 oz. (reg); $350 (long)
Sizes: men’s regular and long, women’s regular ($370)

It’s a chilly morning in the backcountry and the last thing you want to do is exit your warm sleeping bag to step outside. With the Mobile Mummy 800, you don’t have to—you can wear your sleeping bag outside to fire up breakfast or take care of other business. Although the concept of a wearable sleeping bag that converts to a long down jacket isn’t new, Sierra Designs has achieved a nice kind of perfection with the Mobile Mummy.
Sleeping Bag
Big Agnes McAlpin SL (5° F)
$360, $380 long, 2 lbs. 14 oz. (reg)
Sizes: regular and long

What should you look for in a winter sleeping bag? I want it to be warm enough, sure, but I also look for several other attributes, like a little extra space, resilience to moisture, and that it’s not too heavy or bulky and doesn’t cost more than my winter tent. Big Agnes has answered my demands with the McAlpin.
