Features

  • The Sidewinder SL is a side sleeper's dream bag with technical features that roll seamlessly from one adventure to the next—and from one side to the other at night
  • Specifically designed for women who sleep on their sides; technical fit is patterned to move with you as you roll from one side to the other
  • Big Agnes women-specific bags differ in shape and fill weight from the unisex version
  • Women-specific Big Agnes bags have a less drastic taper from shoulders to hips to feet—reducing cold spots and creating more warmth where it counts
  • Big Agnes women's bags are designed to contour to your figure for the most thermally efficient and comfortable night's sleep
  • Body-mapped insulation optimizes warmth where you need it and minimizes pressure points and other "side effects"
  • Down fill with a PFAS-free water-repellent finish throughout the bag provides lofty warmth; synthetic insulation helps alleviate common pressure points in the hips and feet
  • FireLine™ ECO synthetic insulation features low-denier fibers that are tightly woven and provide high loft, compressibility, high weight-to-warmth ratio, and durability
  • Optimized fit and thermally efficient footbox is patterned to mimic the shape of your foot position while lying on your side
  • Improved shell fabric and lining with PFAS-free water-repellent finish
  • Close fitting, jacket-style hood keeps insulation close to the body without sacrificing mobility
  • Easily adjust hood without unzipping using low-profile internal cordlock access
  • Keep your pillow in place with the unique Pillow Barn; it's made of stretch-mesh material with interior access from either side for easy adjustment (pillow not included)
  • Smooth, quick zip with antisnag locking zipper with no-draft zipper garage and long, ambidextrous zipper
  • Seal out drafts by cinching insulated tube along upper hood opening
  • Hang dry or store bag with exterior loops
  • Storage sack and stuff sack included

Imported.
