Description

Many of us change positions during the night or sleep on our sides and traditional sleeping bags don't always cooperate with nocturnal movement. The water-resistant down-insulated Big Agnes Women's Sidewinder SL 20 Degree mummy-style bag provides female backpackers with 3-season warmth while adjusting as you roll around during the night to ensure consistent, reliable warmth.

Contoured to best fit the female figure and address gender-specific areas of potential heat loss, the bag is insulated with 650-fill DownTek hydrophobic down. Down insulation has long been renowned for its compressible properties and efficiency in delivering an excellent warmth-to-weight ratio. The shortcoming of down has been its susceptibility to the effects of moisture, losing much of its performance qualities when wet or damp. DownTek insulation utilizes nano technology and a proprietary application process to provide water-repellency and both anti-microbial and anti-bacterial protection. Using body-mapping for key areas of vulnerability to moisture, Big Agnes applied post-consumer recycled FireLine ECO synthetic insulation to bolster weather protection. A nylon ripstop shell with a DWR finish further protects against the elements while a polyester taffeta lining enhances comfort.

The bag's technical and strategic patterning allows the bag to flex with you if and as you turn and move. While doing so it continues to eliminate "dead" space within the bag that could otherwise create cold spots but never feels restrictive. A jacket-style insulated hood with an internal insulated baffle delivers warmth regardless of your sleeping position. A uniquely designed "pillow barn" comfortably situates a backpacking/camping pillow (pillow sold separately) beneath your head whether you are lying on your back, your right side, or your left side. An insulated draft tube behind the bag's anti-snag zipper keeps cold air out of the interior of the bag.

Available in your choice of Petite (fits to 5' 5") and Regular (5' 10") lengths, the Big Agnes Women's Sidewinder SL 20 Degree sleeping bag includes a stuff sack and a storage sack.

  • Women's specific shape and fit for the most thermally efficient and comfortable night's sleep
  • Specifically designed for people who sleep on their sides with a technical fit, patterned to move with you as you roll from one side to the other
  • Close fitting, jacket-style hood keeps insulation close to the body without sacrificing mobility
  • Keep pillow (not included) in place with unique Pillow Barn made of stretch mesh material with interior access from either side for easy adjustment
  • Optimized warmth and minimized pressure points with body mapped insulation
  • Shell fabric and lining have PFC-free water repellent finish
  • Down fill with a PFC-free water repellent finish throughout the bag provides lofty warmth while synthetic insulation helps alleviate common pressure points in the hips and feet
  • Optimized fit and thermally efficient footbox is patterned to mimic the shape of your foot position while lying on your side
  • Smooth, quick zip with anti-snag locking zipper with no-draft zipper garage, and long, ambidextrous zipper
  • Easily adjust hood without unzipping using low-profile internal cordlock access
  • Seal out drafts by cinching insulated tube along upper hood opening
  • Hang dry or store with exterior loops
  • Storage sack and stuff sack included
