Women Specific Bags

• Men and women sleep better in sleeping bags designed for their body type. Sierra Designs was the first in 1995 to recognize that sleeping bags should be designed differently for women. The average man is 6 feet tall, but the average woman is 5 feet, 4 inches tall. Body proportions and metabolic rates are also different. We size our women's bags smaller so that women are not carrying additional weight and don't have to heat up more air space in a larger bag. Women's sleeping bags are also designed with narrower shoulders, wider hips and increased insulation in the torso and foot box.
• Sierra Designs developed the first women-specific sleeping bags in 1995 (Calamity Jane and Annie Oakley).
• Our women-specific bags are tailored to fit a woman's body (narrower at the shoulders, wider at the hips and sized for height).
• Offer more insulation in the torso and foot box region.
• We offer the most complete selection of Women's specific sleeping bags.
