Therm-a-Rest® Debuts Women’s Sleeping Bags with Reflective Technology

In 2014, Therm-a-Rest expands its award-winning sleeping bag line with the addition of three sleeping bags meticulously designed to meet the unique needs of women and provide them with the best possible night’s rest outdoors.

Therm-a-Rest Mira

Therm-a-Rest’s Synergy-Link™ mattress connectors and innovative ThermaCapture™ technology set the new women’s sleeping bags apart from the competition. The Synergy-Link Connectors—two patent-pending bands that fit mattresses up to 25 inches (63 cm) wide—keep the bag and mattress securely aligned to eliminate problems with sliding, twisting, and cold spots. ThermaCapture is a proprietary reflective lining that captures the body’s radiant heat, amplifying warmth without the weight and bulk of additional conventional insulations. The reflective technology, also used in the brand’s popular NeoAir™ mattresses, allows the bags to rank among the lightest in their temperature rating.

“These new women’s sleeping bags have to be some of the most well-thought-out sleeping bags on the market,” said Doug Jacot, vice president of Therm-a-Rest. “Every aspect of the design was scrutinized through our in-house cold chamber testing and by our team of testers in the field. Our tireless work resulted in designs that provide women the most warmth and comfort possible in bags that are extremely light and packable.”

The sleeping bags feature a unique, women-specific Efficient Comfort Fit with extra room in the torso and hips to allow greater freedom of movement—particularly when side sleeping. The bags are cut slightly closer in the shoulders, head, and feet to maximize warmth. A trapezoidal foot box with Toe-Asis™ foot warmer pocket allows women to rapidly warm cold feet while an overfilled hood, draft collar with drawcord, full-length zipper draft tube, and box-baffled down and shingled EraLoft™ synthetic insulation options maximize the warmth provided by ThermaCapture technology.

Zoned insulation prioritizes high-loft fill throughout the bag’s top to trap rising warm air. Each bag comes with a smaller amount of fill in the bag’s bottom that works in tandem with a three-season sleeping pad to provide users with extra warmth. The result: A bag that’s tuned to match the female body’s natural resting position, stays firmly attached to the pad, and delivers optimal comfort and warmth.

The three new women’s sleeping bags debuting at the Outdoor Retailer Summer Market in Salt Lake City, Utah are:

  • Mira Women’s 15°F/-9°C: At 1lb. 12 oz. (820g), the 750-fill goose down with ThermaCapture Mira bag provides ultralight and compact three-season comfort for women.
  • Adara Women’s0°F/-18°C: At 2 lbs. 6 oz. (1090g), the 750-fill goose down with ThermaCapture bag provides light and compressible cold-weather warmth for four season comfort.
  • Capella Women’s 20°F/-7°C: The 2lbs. 12 oz. (1250g) Capella bag features Therm-a-Rest’s EraLoft™ synthetic insulation—a proprietary blend of three fibers that provide superior warmth, loft and durability—for three-season warmth with all-weather performance for women.

The 2014 line of Therm-a-Rest Women’s sleeping bags will be sold online and at retail stores in January 2014.
