Sea to Summit Flame FM I Women's Regular Sleeping Bag

If you are looking for the lightest bag possible, the products in the Flame range are made for you. The coolest model in this family after the FM0, the SEA TO SUMMIT Flame FM I sleeping bag is designed to keep you warm in temperatures between 4° and 9°C while optimizing its weight and size once packaged.

Female version of the Spark, with a slightly narrower shape at the shoulders than the Spark I, a slightly wider width between the hips and knees and a little additional insulation to provide a little warmth in strategic areas, this model is here offered in a Regular version suitable for women measuring up to 1m70.

To achieve this result, this bag combines Loft RDS 850+ goose down, a small YKKK #3 zipper, high-performance 10D nylon fabrics for the exterior and 7D for the linings. These materials are combined with a sarcophagus-shaped design for effective insulation. In addition, the padding has been placed vertically to prevent it from moving and creating cold zones.

The Flame FM I also benefits from a water-repellent treatment protecting the down from external humidity and condensation inside the sleeping bag, virtually eliminating the negative effects of humidity on the down. This protection also makes it possible to use this model in adventure raids or in difficult alpine conditions, where every gram is counted and where until now natural down was not a viable option.
