Sea to Summit Flame Series - Women's Down Sleeping Bag

Extremely compact bags designed for maximum warmth and minimal weight.

The Flame Series includes everything from an ultralight liner to an expedition weight mid-winter bag, with a Women's specific shape for efficient insulation.

This is the Women's version of the Spark series. You can explore the Men's specific Spark Series here.

The secret to the impressive performance is a combination of premium materials and careful design. The RDS 850+Loft premium goose down, light-gauge #3 YKK zip and high-performance 10D Nylon shell and 7D lining fabrics set the stage for superior performance. These materials are combined with a contoured mummy design for efficient insulation, and that mummy design is then tweaked for each model to best fit the use scenario.

The women’s specific fit is wider at the hip and narrower at the shoulder and we’ve added extra down overall for increased warmth.

ULTRA-DRY Down water-repellent treatment protects the down from external moisture and condensation from the inside of the bag, virtually eliminating the negative effects moisture has on down. All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down. The ULTRA-DRY Down protection also makes the Flame an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option.

Temperature Rating

EN Rating

The EN13537 is a European standard for sleeping bags that provides three temperature levels to help guide you when choosing a bag.

Comfort: The temperature at which a standard woman can expect to sleep comfortably in a relaxed position. If you are female or consider yourself a cold sleeper, use this rating to decide the coldest temperature the sleeping bag is suitable for. We emphasise the Comfort temperature for our women’s specific sleeping bags.

Lower Limit: The temperature at which a standard man can sleep for eight hours in a curled position without waking. If you consider yourself a warm sleeper, use this rating to decide the coldest temperature the sleeping bag is suitable for. We emphasise the Lower Limit temperature for all our unisex sleeping bags.

Extreme: This is a survival only rating for a standard woman. Between the lower limit and the extreme rating, a strong sensation of cold must be expected and there is a risk of health damage due to hypothermia. This is an extreme survival rating only; we do not recommend you rely on this rating for normal use.
