Sea To Summit Flame III Ultralight Women's -4° Sleeping Bag Regular Dark Grey & Paprika

Ultra-light and technical, the Sea To Summit Flame Series sleeping bags are designed to keep you as warm as possible while minimising packed weight and size. The Flame Series spans everything from an ultralight liner to an expedition weight mid-winter bag. While the end usage is very different, they reflect a design ethos of matching weather conditions to the lightest bag possible.

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. The women specific fit design feature a comfortable broader mummy shape which is narrower at the shoulders and wider between the hips and knees, additional insulation compared to unisex bags, a snug-fitting 3-dimensional hood, oversized draft tubes to prevent body heat escaping, and super-soft fabric. The ULTRA-DRY Down water-repellent treatment 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.
