10 Best Down Sleeping Bags for Backpacking in 2024

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 and hybrid sleeping bag picks at a variety of price points.

Be sure to read our recommendations below on how to choose the best sleeping bag for your needs.

1. REI Magma 15 (unisex)

REI Magma 15 Sleeping Bag
The REI Magma 15 is a lightweight and compressible 850 fill-power down sleeping bag that’s loaded with features. It has a trapezoidal footbox with body-mapped baffles for maximum warmth retention while reducing weight. The bag has an insulated draft collar while the hood has a pillow pocket and two drawcords for flexible adjustment. A hybrid zipper path provides easy access along the shoulders and torso and the zipper is backed by an anti-snap strip for worry-free use. The REI Magma is also available in a 30-degree version.

Rather than make a men’s and women’s version of the Magma 15 and Magma 30, REI now offers these sleeping bags in nine sizes (yes nine) so you can choose a bag that’s optimized for your dimensions irrespective of your sex which is the real metric on which men’s and women’s bags are designed. That said, I’d recommend trying this bag in an REI store if you want a perfect fit.

2. Western Mountaineering Versalite 10 (unisex)

The Western Mountaineering Versalite is a warm and spacious sleeping bag with plenty of interior room. It has continuous baffles so you can move the down where you need it most, on top on cold nights, and to the bottom of the bag on warm ones, thereby expanding its temperature range.  A full-length zipper makes it easy to vent on warmer nights, while an insulated draft collar seals in the heat. A “flattish” mummy-style hood is also easier to use for side sleepers. The Versalite is available in three lengths: 5′ 6″, 6′ 0″, and 6′ 6″. Insulated with 850+ fill power goose down, it weighs in at just 32 ounces. It’s available in three lengths, making it ideal for backpackers who hike in cool mountain climates.

Parsec 20
The Therm-a-Rest Parsec 20 is a very warm but lightweight 800 fill-power (hydrophobic Nikwax treated) down sleeping bag suitable for three-season use. It has bodymapped insulation with 60% of the down positioned over the chest and 40% on the bottom to reduce weight and provide enhanced warmth when used with an appropriate sleeping pad. The Parsec 20 has a draft collar and zipper draft tube to hold in your body heat with a two-way zipper so you can vent the bag if you feel too warm. Special sleeping pad straps help prevent you from rolling off your pad at night, while exterior loops let you layer compatible quilts or technical blankets on top to boost the Parsec’s temperature rating. Read the SectionHiker Parsec review.

A two-way anti-snag zipper gives you the option to vent the bag if you’re too warm, while an anatomically shaped trapezoidal foot box keeps your feet from compressing the insulation and creating cold spots. The Phantom 15 weighs 31.8 oz and is cut slim to keep it as lightweight as possible for summit attempts. Right-hand and left-hand zipper models are available and a lightweight compression sack and mesh storage sack are included.

The Ultralight Bed is available in multiple sizes and at multiple temperature ratings. Everyone I know who’s bought a Zenbivy sleep system, including very experienced backpackers, raves about it! See our review of the Zenbivy Light Bed, which is very similar.

7. Feathered Friends Flicker UL 20 (unisex)

Feathered Friends Flicker 20 UL
The Feathered Friends Flicker UL 20 is a highly versatile hoodless sleeping bag that’s ideal for side sleepers who find a mummy bag claustrophobic. In cooler weather, the Flicker functions as a full center-zip mummy sleeping bag with a heat-saving down-filled draft collar that drapes around your neck and over your shoulders to seal in heat. It has a drawstring foot box that can be cinched tight on cooler nights or opened up to vent the bag if you’re too warm. Unzipped, it can be flipped over on warmer nights and used like a quilt or a blanket since the foot box opens completely. Insulated with 950+ fill power down, the 20ºF Flicker has continuous baffles that let you move the down insulation to where you need it. Weighing 26 oz, it’s perfect for cool summer nights in alpine terrain and thru-hikes. Read the SectionHiker Flicker Review.

The Egret has a draft collar to help seal in the heat around your shoulders, with a trapezoidal foot box that allows your feet to fall in a natural pose without compressing the sides. Available in two lengths: 5′ 3″ and 5′ 9″, the Egret UL 20 is insulated with 950+ fill power goose down and weighs just 27 oz.

9. Enlightened Equipment Convert (unisex)

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.

10. REI Magma Quilt 30 (unisex)

REI Magma 30 Quilt
The REI Magma Quilt 30 is a good bet for warmer weather use because it offers the snug warmth of a mummy bag but with great ability to adjust your warmth as needed. The magma Quilt is insulated with water-resistant 850-fill-power goose down with a supersoft Pertex shell fabric. Like premium sleeping bags, it has an adjustable, insulated draft collar that can be cinched around your neck to keep warm air in and has a roomy trapezoidal foot box to keep your feet comfy and warm. Pad cords let you adjust fit and warmth and keep you centered on your sleep pad all night (we recommend using an inflatable pad for maximum comfort.)

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.
