The innovative Sierra Designs Women’s Backcountry Bed 600F 3-Season zipperless sleeping bag provides campers with similar comfort to their beds at home whether they’re back, side or stomach sleepers. Featuring 600 fill duck DriDown water-resistant down and strong polyester ripstop shell fabric, the Women’s Backcountry Bed 600F 3-Season is a high-quality, comfortable bag with female-specific construction details for 3-season use that won’t break your budget.
Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel, and despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but the DriDown featured in the Backcountry Bed 600F 3-Season bag performs differently. Employing a unique, innovative polymer application, DriDown actually creates a hydrophobic finish on each individual plume of down. This treatment results in insulation that stays dry up to 10 times longer and dries 33% faster, should it become wet, than untreated down bags.
In addition, gender-specific construction on the Women’s Backcountry Bed 600F 3-Season bag offers a fit that is more proportional between the shoulder and hip girth for better thermal efficiency and includes a higher level of insulation to help offset a woman's natural tendency to sleep colder than a man.
By eliminating zippers, Sierra Designs has created a sleeping bag that’s more similar to your down comforter at home than a traditional sleeping bag, though without your comforter’s annoying ability to shift off your body in the middle of the night as you move. Get in the Backcountry Bed through the unique catenary shaped opening that’s smaller than bag width to seal out drafts even when you’re shifting inside. Once settled in, the versatile integrated comforter fits naturally around you and conforms to your preferred sleeping position while also allowing you to easily adjust for varying temperatures. Insulated pockets in the comforter provide a cozy place for your arms and hands to stay warm if you’re not cocooned down inside the bag, or tuck the sides of the comforter around and beneath you when the temperature drops to be fully ensconced; the top of the bag also allows you to tuck your head inside for insulated warmth much like a hood. A unique zipperless foot vent allows you to extend your feet out of the bottom of the bag in balmy weather but effectively retains heat when temperatures require it.
Beyond the zipperless construction, the Women’s Backcountry Bed 600F 3-Season has no additional cords or Velcro to get in the way of comfort, though it does feature a sleeping pad sleeve on the bottom to allow you to even better create a bed-like sleeping experience while spending the night outside.
The Sierra Designs Women’s Backcountry Bed 600F 3-Season sleeping bag fits individuals up to 5' 8" tall. A stuff sack and storage sack are included.
