The Best 3-Season Sleeping Bags (15F-29F)

Our experts tested the best sleeping bags in the following three temperature ranges: summer sleeping bags (30 F+), three-season sleeping bags (15-29 F) and winter sleeping bags (0-14 F).

We tested versatile three-season sleeping bags in 2015 and 2016 by bringing them on trips in the Ozark Mountains, the Cascades and Olympic National Park. We reviewed both women’s and unisex models. In those tests, the top-rated products were:

Montane Minimus Sleeping Bag

The Montane Minimus may be the best sleeping bag in our test, but it can also be the hardest to find. The British brand lacks the broad distribution of bigger, better known US brands, but the Minimus is worth tracking down. The Minimus proved the most comfortable bag I tested, as well as one of the lightest, most durable, and warmest. Only the feather-weight Sea-to-Summit bag was lighter, but it lacked the comfort. And while the REI Lumen and Big Agnes Lost Ranger impressed our test team with similar comfort, they were each nearly a pound heavier that the Minimus.

Montbell Down Hugger 800 #1 Sleeping Bag (800-fill Down)

Montbell’s Down Hugger #1 is a warm and compressible bag that incorporates Montbell’s spiral stretch making the bag very flexible and comfortable.  But taller users will need to look to another bag.

Millet 7 Summits Down Sleeping Bag

The Millet 7 Summits sleeping bag is a comfortable, warm bag with a great tapered design and excellent loft. The 7 Summits was the warmest of the bags tested in this category, but this warmth will cost you a bit more money.

what is a Three Season Sleeping Bag?

by: Last Updated:

A three-season sleeping bag is the most versatile option for backpackers and campers. With a comfort range between 15-29 degrees Fahrenheit, these bags will feel right for the widest range of seasons and elevations. Three-season bags will be warm enough for summers in the mountains and fall evenings in the desert, but won’t feel like overkill on a balmy summer night under the stars. Three-season models strike an excellent balance of light weight, comfort, and packability; being smaller and lighter than thick winter bags but warmer and cozier than thin summer bags.

If you are shopping for a sleeping bag and only want to purchase one and not a quiver, the three-season bag is the jack-of-all-trades bag you are looking for. You can find bags in this temperature range with both down and synthetic insulation and in a range of shapes and styles. There are also many women’s specific three-season bags on the market, which tend to be a little shorter and cut slightly wider around the hips and narrower around the shoulders to better fit a woman’s dimensions.
