Big Agnes King Solomon 15 Degree Double Wide Sleeping BagMSRP: $449.95 1 of 6
This double wide sleeping bag is perfect for a couple's camping trip. Unlike many duo sacks, the King Solomon has a zipper on each side for easy exit/entry for both parties (key for those midnight bathroom runs), as well as an extra 5cm of foot box length for you tall folks.
A key feature of this sack is the integrated pad sleeve, which means you no longer have to wake up in the middle of the night realizing you have rolled off your pad and onto the cold, hard ground. This bag will keep you toasty in even the coldest conditions, and its center no-draft flap and no-draft collar mean even the most active sleeper will be kept insulated through the night.
Aektiv Outdoors 15 Degree Mummy Style Sleeping BagMSRP: $95 2 of 6
A reasonably priced option for light backcountry expeditions in the winter, spring and fall, this mummy-style sleeping bag is super plush and quite compact when rolled up. At just around 3 lbs while compressed into its carry sack (which is actually a nice backpack in its own right), this bag is a great option for multi-day hikes or for families trying to minimize car space while headed outdoors.
It's inside cellphone/wallet pocket is a sweet little addition and comes in really handy not only for security, but also when you've got to answer that call but really don't want to have to leave your warm sleeping bag to reach your phone.

The Women's Cat's Meow Sleeping BagMSRP: $199 4 of 6
The Cat's Meow line from The North Face continues to be the quintessential backcountry sleeping bag, and their newest iteration doesn't disappoint. One of the more stylish sleeping bags you'll see at the campsite, the Cat's Meow keeps you warm and snug in 20+ degrees F temperatures through their patented Heatseeker Pro insulation. The cyclone construction saves on weight and traps in heat more efficiently, while the internal hand warmer pockets are a nice, snazzy touch that you don't realize you'd been missing in a sleeping bag until you've tried them.
NEMO Sonic Sleeping BagMSRP: $459.95 5 of 6
If you're headed to K2—or just like to look like you are—then chances are you're not going to balk at dropping this kind of dough on sleeping bag technology. Winner of the 2015 Backpacker magazine Editor's Choice Award, this whopping 850-fill cold weather sack uses adjustable "Thermo Gills" to regulate your internal temperature by as much as 20 degrees F without letting cold drafts get inside.
The stretch construction at the knee-area makes it possible to sleep comfortably in a side or knees-bent position, and the nylon shell has a light weatherproof coating to keep you dry in damp conditions. All of this technology still collapses up surprisingly small and lightweight, making this a great choice for the serious winter explorer.
