The Ascent -9° is by no means the smallest packing sleeping bag, but it is light. The Ascent series offers the relaxed mummy shape ideal for those who don't like the confinement of a mummy or are side sleepers. With an extreme low of -15° this bag is more than capable of handling New Zealand's winter alpine conditions and is one of the warmest in our range. However, the Free-Flow zipper configuration allows you to regulate temperature and makes it more useable in warmer temps compared to other sleeping bags with a single-half zip and the same temperature rating - but don't worry the wind won't be able to cut through the zipper draft tubes!

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).
