  • Semi-rectangular women's-specific fit is designed for spacious comfort when you're camping or traveling: slightly narrower at the shoulders and roomier through the hip area. Regardless of the position you sleep in (figure-four, on your side or on your stomach), this shape provides a significantly higher level of comfort by giving you the room to move without compressing the insulation.
  • Women's sleeping bags have additional insulation compared to unisex bags, positioned using different body mapping for thermal performance exactly where it is needed
  • Sustainable construction with 100% recycled bluesign®-approved 20D polyester shell and lining, a PFAS-free water-repellent coating and RDS down
  • 650+ Fill Power, RDS-certified, Down with ULTRA-DRY Down treatment for improved water resistance in damp conditions
  • Free Flow Zip System for reliable, snag-free operation, to provide superior ventilation and allow the bag to be used as a comforter/quilt:
    • Primary zip: full-length #5 zip with zip-plow and two sliders
    • Secondary zip: half-length #5 zip with zip-plow and two sliders
    • Foot box zip: #5 with two sliders
    • Vertical chest baffles, horizontal baffles lower half and base, box wall baffle construction throughout
    • Generous fitted hood with two soft touch adjustments; fits a Sea to Summit regular pillow

ULTRA-DRY Downâ„¢: With the introduction of water-repellent ULTRA-DRY Downâ„¢ Seat to Summit have virtually eliminated the negative effects moisture has on down. The ULTRA-DRY Downâ„¢ water-repellent treatment protects the down from external moisture and condensation from inside the bag. It is a permanent (no loss of treatment effect has been seen in over 14 wash cycles) Nano-level water repellent polymer treatment applied to Sea to Summit high loft, high quality down. The Nano-thin treatment vastly improves the down's reaction to water without effecting its weight or loft performance. ULTRA-DRY Downâ„¢ retains over 60% more loft and absorbs 30% less moisture when compared with untreated down. Sea to Summit sleeping bags dry out 60% faster than bags with untreated down. The Nano-level treatment also inhibits bacterial and microbial growth, which makes Sea to Summit sleeping bags more hygienic and improves their lifespan.

Responsible Down Standard (RDS): The RDS is helping to shift the entire down and feather industry towards more humane animal rearing and handling practices. Overseen by the industry leading Textile Exchange, the RDS requires independent, third party assessments of all aspects of animal rearing and handling throughout the entire supply chain. By only using down that meets the audited requirements of the RDS we can have confidence that each phase of the collection process has been completed with the welfare and ethical treatment of waterfowl in mind. To find out more about how the RDS is improving animal welfare during down collection, please visit responsibledown.org (link will open a new window).
