The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. The test produces a Lower rating (for male sleepers) and a Comfort rating (for female sleepers). Both are listed in the features table on the product page.
A unisex sleeping bag with a Lower limit of -10°C means a man should be comfortable down to air temperatures of -10°C. The same bag will also have a Comfort limit, in the realm of -3°C, so a woman would be comfortable down to an air temperature of -3°C. These ratings require a sleeping mat with an R-Value appropriate for expected ground temperatures – without this, the sleeping bag itself is unlikely to keep the sleeper warm enough.
A variety of factors impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag, an appropriately insulating sleeping pad and a liner as a sleep system. For example - if you plan on sleeping in nighttime air temperatures of -3°C, choose a bag with a gender-appropriate rating of -5°C, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.
The versatility of the Flame Ultralight Women's Sleeping Bag Series spans from an ultralight down-filled liner to a mid-winter fast-and-light sleeping bag. Each model uses premium materials and design to provide cutting-edge performance.
The women's specific mummy fit is narrower at the shoulder and wider at the hip, and features extra down compared to the unisex Spark models.
DESIGNED FOR WOMEN
Shaped for comfort
Narrower at the shoulders, wider between the hips and knees. Regardless of the position you sleep in (figure-four, on your side or on your stomach), this shape provides a significantly higher level of comfort by giving you the room to move without compressing the insulation.
Warmth from additional insulation
Additional insulation compared to unisex bags, positioned using different body mapping for thermal performance exactly where it is needed. Temperatures for Women’s sleeping bags are shown using the gender appropriate Comfort rating.
Maximum comfort for a good night's rest
Construction details like snug-fitting hoods and oversized draft tubes keep you warm in cooler weather. Super-soft fabrics are comfortable in any season.
You don’t have to narrow your options with a constrictive mummy bag – expand your horizons with a sleeping bag which fits the way you sleep.

The highest-lofting down used in any of Sea to Summit’s sleeping bags. 850+ Fill Power indicates that one ounce (30g) of down will re-expand to over 850 cubic inches after compression. Higher loft means that less down can be used to achieve the same temperature rating – important for performance sleeping bags. The loft and down quality/composition are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is supplied with every Sea to Summit sleeping bag. The down is responsibly sourced and RDS certified and treated with the environmentally-friendly Ultra-Dry Down treatment.
100% of the down used in our sleeping bags and quilts is independently certified to the Responsible Down Standard (RDS). The RDS certifies down against animal welfare requirements and tracks it from the source to the final product. The purchase of RDS certified products demonstrates demand for better animal welfare practices in the down and feather supply chain. Sea to Summit is certified to the RDS.

Ultra-Dry Down is a non-PFC treatment hydrophobic treatment applied to the down during down processing. It is not a coating (which would reduce the ability of the down to loft), it comprises of very small particles of a polymer that cause the down clusters / feathers to repel water. Ultra-Dry Down is PFC and PFAS-free. Hydrophobic down is not waterproof; but it absorbs less water than untreated down and dries much more quickly.
Ultra-Dry Down does not affect the loft or lifespan of the down, or its breathability. The treatment will last through at least 20 washings.
Despite being incredibly lightweight, the 10 Denier UL Nylon is down-proof and surprisingly durable. A DWR finish helps to shed external moisture. This fabric is part of the secret to making the Spark and Flame Down Sleeping Bag Series some of the lightest, most packable sleeping bags available today.
Our women's specific bags feature a distinctive shape designed to provide more comfort and the best thermal efficiency. The designs are ideally suited to a woman's shape - slightly narrower in the shoulders and roomier through the hip area. Down distribution is perfectly matched to ensure the torso and the foot areas are kept toasty warm.
Frequently Asked questions
Suitable for cooler temperatures?
Yes. Choose the Flame 15°F or 25°F for use up until the late Fall. The 15°F will take you down to early winter temperatures when paired with a greater than 3.5 R-Value insulated sleeping mat.
Really suitable as a sleeping bag liner?
Yes. You could use the Flame 55°F, or even the Flame 48°F to boost the performance of a bag for cold-weather use. Tip: add one of these to a 20°F sleeping bag instead of buying a 0°F sleeping bag for occasional winter use.
Able to be zipped to another sleeping bag?
No. Even though the 25°F and 15°F have full-length side zippers, they are not designed to be coupled to a sleeping bag with a left zipper.
