Choosing the right sleeping bag for a spring camping trip can be tricky because it is such a fickle season. Many parts of the United States see freezing temperatures and snow as late as May—even later in the mountains. So, for spring camping, you’ll want a sleeping bag that will keep you warm in cold weather but won’t sweat you out on warmer nights. For those who don’t mind dropping almost $300, The One Bag from The North Face makes an excellent addition to a spring sleep system. The One Bag consists of three zippable, down-filled layers, allowing you to change from a 5° F. configuration to a 20° F. setup to a 40° F. arrangement on warmer nights. Although it’s rated for temperatures as low as 5° F., reviewers have noted that 15° to 20° F. is really about the bottom of this bag’s comfort range, so depending on where you live, it may be more of a three-season bag in spite of the manufacturer’s rating.
For those looking for a similar bag at a more budget-conscious price, The North Face makes a recycled-synthetic version of The One Bag for its Dolomite line. The Dolomite bag is rated at 15°, 30°, and 50°, depending on how its configured, and comes in at less than half the price of its down sibling.
