Unless you live in truly warm temps, we tend to think at least one shared sleeping bag is a necessity in your go-bag. (Mylar blankets are the other lightweight option, but are super flimsy.) When you're looking for a sleeping bag, you want something light and packable, but also as versatile as possible. This bag is light-weight 1.6 pounds — rated to 20 degrees Fahrenheit. (You can get even lighter versions such as the Flicker 40, but isn't as warm. You can always wear warm clothes or base layers inside, too, of course.) However, one feature we like best is that it completely unzips to form a quilt — which you could use to cover two adults or several children provided there is a warm base layer underneath.
Flicker 20 UL Quilt Sleeping Bag
Importance: Handy to important, esp. if you face colder climes.
Bottom line: At least one good sleeping bag is great to have in your go-bag. Lighter is better. This one weighs less than 2 pounds and also fully unzips into a quilt.
Recommended for: Go-bags.
You’ll also need: An underlayer, like a foam or blowup pad, which makes it even warmer, and also gives you the option of unzipping it and using as a quilt to spread over several people.
Be aware: The 20 is rated to 20 F, the 40 version to 40. This one doesn't have a top head section like a tradtional mummy bag, so your head might get cold if you don't have a hat.
