10 Best Down Sleeping Bags for Backpacking in 2022

10 Best Down Sleeping Bags for Backpacking

Down insulated sleeping bags are still the most popular nighttime insulation option with backpackers because they’re highly compressible and warmer in cold, damp, or drafty weather particularly in the spring and autumn when temperatures are close to freezing. While mummy bag designs still prevail, there’s a lot more variety in the types of sleeping bags that have become available in the five years, including ones designed for side sleepers, women’s specific sleeping bags, and hoodless quilt-style sleeping bags.

When choosing a sleeping bag for backpacking, you want one that’s lightweight and highly compressible since you’re going to have to haul it in a backpack. Sleeping bags insulated with 800-950 goose or duck down are the best in terms of warmth by weight, but you’ll pay a premium at the top end.

Here are our top 10 down sleeping bag picks including men’s and women’s specific bags.

9. Enlightened Equipment Convert Sleeping Bag

EE Convert Sleeping Bag
The Enlightened Equipment Convert is a hoodless, quilt-style sleeping bag with a full-length zipper and drawstring foot box that allows it to be completely closed like a hoodless sleeping bag, completely open like a down comforter, or partially zipped up like a backpacking quilt. It’s insulated with RSD-certified 850 fill power down and has a snap and drawcord neck closure that lets you fine-tune draft control. The lack of a hood makes it a great choice for side sleepers while the full-length zipper and foot box gives it more temperature flexibility than a quilt or sleeping bag alone. When ordering you can specify the temperature rating or width you’d like. For spring and autumn weather, we’d recommend a 10 or 20 degree bag, since it’s so easy to vent for warmer weather. For women, we suggest adding another 10 degrees worth of insulation. Read the SectionHiker Review.

Sleeping Bag Purchase Criteria

Here is a list of the most important factor to consider when purchasing a sleeping bag for backpacking, so it fits your needs and preferences.

TEMPERATURE RATINGS: The introduction of standardized sleeping bag temperature ratings by the outdoor industry substantially improved their reliability. Bags tested with the European Norm (EN) 13537 get two ratings: a Comfort rating and Lower limit rating. The Comfort rating is the lowest temperature at which the bag will keep the average woman (or “cold sleeper”) comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep an average man (or “warm sleeper”) comfortable. The difference in the Comfort and Lower Limit ratings is usually about 10 degrees since women feel colder than men when sleeping. If you’re a woman and decide to buy a men’s or unisex bag, get one that’s 10 degrees warmer than you need so you’re comfortable at night

INSULATION and COMPRESSIBILITY: High-quality goose and duck down with fill powers of 800, 850, 900, and 950 provide excellent insulation by weight and are widely preferred by backpackers and base campers because they’re so lightweight. Some manufacturers only offer down that’s been treated with a water-repellent coating, while others prefer to offer it unadulterated. Down is naturally water-resistant so the jury is still out on whether “treated” down makes a difference in the long-term since it’s easy to keep your sleeping bag dry with a little care.

SIZING: The fit of a sleeping bag is usually measured in terms of length and girth. Girth measures the maximum internal circumference of the bag, usually at the shoulders, hips, and feet. Measure yourself at these points and compare them to the girth to see if the bag will fit tightly or loosely. People with bigger shoulders or sides sleepers tend to feel more comfortable in bags with higher shoulder girths, while women typically need a shorter length bag and a smaller shoulder girth because they have narrower shoulders than men. It’s important to get a bag that minimizes the amount of unoccupied interior space relative to your measurements, so your body has less air to heat up to stay warm. If a bag is too large, it will feel colder than one that fits closely, since your body needs to work harder to fill the extra space with hot air.

WEIGHT: While gear weight is important, be careful not to sacrifice your comfort by selecting a sleeping bag that won’t keep you warm or dry in the conditions you need it to.  When choosing between bags with different outer shell fabrics, consider their breathability, so they will vent perspiration that can degrade your insulation, and whether they have a DWR coating, which can be important if the foot of your quilt gets wet regularly.

FEATURES: Most sleeping bags are pretty similar when it comes right down to it, but there are some features that set premium sleeping bags better than nonpremium bags. These include draft collars, continuous baffles, very high fill-power goose down, non-snagging zippers, draft tubes positioned behind zippers to seal out the cold, ventable foot boxes, and full-length zippers that help extend the range of a bag in warmer weather.

  1. At 6’2″, I love my long Western Mountaineering Versalite. The 10 degree rating is generous in my opinion. I got the 6’6″ version which allows ample space for boot liners, water bottles and other things I want to keep warm. As an Al fresco hiker, My only wish is that it were a little more windproof.. But they have other models that offer more wind and rain resistance.

  2. Hi. I enjoy your site and want to thank you for all the information. I would like you guys to take a look at Kuiu equipment and maybe add to some of your articles. There may be some pushback because they are a hunting gear company. But, if we can get past that…you’ll be impressed by their lineup. I’ve used them for years and they consistently outshine most other lightweight components.

    • I like their stuff. We’ve written some content on hunting gear, including a KUIU clothing review, and it’s been very well received. I like the stuff because it tends to be far more durable than a lot of UL backpacking gear and its designed for cross-country and off-trail travel, which is something I enjoy. Thanks for the suggestion.
