6 Best Sleeping Bags for Women

Sleeping bags are still the most popular nighttime insulation option with backpackers because they’re warmer in cold, damp, or drafty weather, especially below freezing. While mummy sleeping bag designs still prevail, there’s a lot more variety in the types of sleeping bags that have become available in the past five years, including women’s specific sleeping bags. Is it worth buying a women’s specific bag? You betcha, but they’re not as widely available as sleeping bags for men.

Women require more insulation than men because they have less body mass to generate body heat. Add another 10 degrees if you’re female and decide to buy a “unisex” sleeping bag instead of a women’s specific bag. Women also tend to have colder extremities, like feet, hands, and heads, and require more insulation in those areas. They also have narrower shoulders and are predominantly shorter, requiring sleeping bags that are cut differently than their male counterparts.

When choosing a sleeping bag for backpacking, you want one that’s warm, lightweight, and highly compressible since you’re going to have to haul it in a backpack. Sleeping bags insulated with 800, 850, 900, and 950 goose or duck down are the best in terms of warmth by weight, but you’ll pay a premium at the top end. Fit is also important, both width and length, especially if you’re a short women or have a smaller build. 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.

How to ChooseWomen’s Sleeping Bags

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.

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.

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.

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 non premium 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. I think I always leave this comment when you specifically call out women’s gear, but thanks!

    I’ve switched to a quilt for 3 season use, but I’ve never felt like my winter bag was truly warm enough. I may have to look at selling it and investing in something different.

  2. Thank you for posting this review. I have an older (~5 years) Marmot women’s down bag that I am happy with EXCEPT for its snaggable zipper. So I think that it is good that you mention zipper features.

  3. I have a unisex bag (WM Ultralite) but it works for me. The FF bag looks great, but I have no reason to change what I have.

    IMHO, the draft collar (around the neck, allowing the hood opening to be a bit larger to prevent condensation around the hood) is worth at least another 5* of rating!

  4. I see the REI Magna 17 has a 15 denier Pertex lining, which I imagine would feel pretty nice. What are your thoughts with regards to some bag/quilt offerings that use 10 denier for the outer fabric? Should a person have concerns with it being to thin or not robust enough?

    • It’s hard to say actually. While denier is somewhat correlated with durability, it not always the case that thinner thread diameters mean less durability.
      Regardless, I wouldn’t really worry about it too much. Most people don’t use a sleeping bag often enough for it to matter that much or in conditions where wear and tear are that significant.

  5. Montbelle down hugger is by far my favorite. No more feeling like I sleep in a mummy. It has spiral stretch thread that stretched with you. Especially if you like to sleep on your side or sit up in your bag with your legs crossed and enjoy your coffee in bed!
