The new Trek™ TKII Sleeping Bag has vertical baffles in the chest area so the ULTRA-DRY Down™ 650+ loft duck down stays put with a side baffle maintaining a 60/40 fill ratio so that there is more down on the top of the bag for maximum insulation. Other features include lightweight fabrics to cut down on weight and packed size, a panelled hood with a drawcord for when you need the extra warmth and a foot zip for ventilation which, along with the full-length side zip, allows you to use the bag as a quilt. The perfect compromise between comfortable roomy bags and warm trim-fit mummy bags for your camping and adventure travel adventures.

ULTRA-DRY Down™: With the introduction of water-repellent ULTRA-DRY Down™ Seat to Summit have virtually eliminated the negative effects moisture has on down. The ULTRA-DRY Down™ 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 Down™ 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.
