Sierra Designs Solar Flare 15 Degree Women's (2008) Sleeping Bag

Product Highlights

Updated for 2008! The Sierra Designs Solar Flare 15 Degree Women's sleeping bag couples lightweight, compressible down insulation with an innovative waterproof, breathable shell. The Solar Flare 15 Degree Women's bag mirrors the construction of Sierra Designs' award-winning Trade Wind 15 Degree bag with a design that is tweaked to meet the needs of female backpackers.

Having developed the first women-specific sleeping bags back in 1995, Sierra Designs early on realized the differences between male and female campers and hikers. By offering sleeping bags that are tapered to be narrower at the shoulders, wider at the hips and adjusted for height differences, Sierra Designs has created a line of bags that cater to women. Increased insulation in the torso and foot box regions also reflects the results of research into what women want and need in a sleeping bag.

The Solar Flare 15 Degree Women's sleeping bag is insulated with 600-Fill goose down. Down not only has a soft, comfortable feel, it has the best warmth-to-weight ratio of any insulation available. The feathers and fibers are renowned for their efficiency in trapping body heat and are very easily compressed, taking up less space in your backpack. Fill power is a measurement of the loft or "fluffiness" of down insulation. Specifically, fill power is the cubic inches of space occupied by one ounce of down. The one weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet. Sierra Designs has addressed this concern by using waterproof Drizone fabric for the exterior shell of the Solar Flare 15 Degree Women's bag, ensuring that the fill stays dry and performs optimally.

The Solar Flare 15 Degree Women's sleeping bag utilizes a baffle construction in which panels are created by stitching the inner liner and outer shell together to form horizontal tubes. The tubes increase the effective life expectancy of the Solar Flare 15 Degree Women's bag by making certain that the down remains distributed evenly throughout the sleeping bag, insulating your entire body without risk of cold spots from a lack of fill. The foot box of the Solar Flare 15 Degree Women's bag is lined with Tricot. Not found on Sierra Designs men's sleeping bags, this fleece lining adds warmth and helps to prevent cold feet.

Features abound on the Solar Flare 15 Degree Women's bag. Built-in pad locks help to keep you from rolling off of your sleeping pad while you sleep. Sierra Designs' innovative snag-free zipper tracks protect the liner by creating a barrier which prevents stuck zippers. An integrated hood reduces heat loss. A fully-insulated draft tube sewn behind the zipper keeps cold air from reaching the inside of the sleeping bag.

The Sierra Designs Solar Flare 15 Degree Women's sleeping bag is available in Regular (fits up to 5'5") and Long (fits up to 5'11") lengths. A stuff sack is included.
