Sea To Summit Ascent ACI Sleeping Bag

Light, warm, comfortable and most importantly, adaptable. The Ascent™ is our sleeping bag of choice for most adventures, most of the time. Offering the perfect backpacking balance of comfort vs weight, our Ascent™ Series sleeping bags have more space than traditional mummy bags, yet still provide the thermal efficiency you need when exploring above the tree-line.

The Free-Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it’s not. The half zip on the right side of the bag provides freedom of movement for both arms, additional ventilation and means the top third of the bag can be folded down as a mini quilt. The full length, two-way left side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected.

If it’s warmth you’re after, close all the zips, pull the cord locks tight to drag everything in, and relax in luxurious comfort. The generous allocation of high quality 750+ Loft down ensures great insulation, while the oversized draft tubes prevents your body heat escaping. The panelled footbox and 3-dimensional hood make sure you’re not compressing the down when you’re trying to stay

warm. Vertical baffles over the chest section ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation.

Technology:

RDS:
- Sea to Summit is excited to announce that in 2016 all of our Sleeping Bags will use down that has been sourced and certified by the Responsible Down Standard (RDS).
- The RDS is a tool that is going to help shift the entire down and feather industry towards more humane animal rearing and handling practices. Overseen by the internationally lauded Textile exchange, the RDS requires independent, third party assessments of all aspects of animal rearing and handling throughout the entire supply chain process. 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.
- This means no live plucking and no force feeding, humane living conditions and proper animal handling, from the moment of hatching throughout the life cycle of the waterfowl, and through the entire down supply chain.
- In addition, The RDS will be central in helping to increase awareness about what might be happening to waterfowl as their down is harvested. We hope that you, like us, believe that the ethical treatment of animals is important, and can appreciate the importance of the RDS for achieving this in our industry.

750+ Loft:
- Loft is the volume for a given weight of down. It is used to describe the quality of down, relating directly to the insulating performance. High loft down is warmer for a given weight than low loft down. Higher lofting down will fill a larger volume of space for a given weight. As a result, less down weight is required to fill each baffle in a sleeping bag. This translates to a lighter sleeping bag. The most common measure of loft is called Fill Power. 850 Fill Power implies that one ounce of this down will loft to fill a volume of 850in3.
- 750+ Loft Premium Down: In the Sea to Summit Talus and Traveller series, our 750+ Fill Power Premium duck down is a high quality insulation that sets the benchmark for sleeping bags in this class.

ULTRA-DRY Down:
- All Sea to Summit sleeping bags are sold with an International Down Feather Laboratory (IDFL) certificate that identifies the exact Fill Power of the down used. We guarantee our sleeping bags are filled with premium down that exceeds the stated Fill Power in accordance to the International Down Feather Bureau (IDFB) standard.

- Repels moisture
- Retains loft
- Dries faster
- Anti-bacterial and anti-microbial
- Prolongs the life of your sleeping bag

- In a world of technical brilliance, it is remarkable that the performance of certain natural products have not been surpassed. Despite advances in modern fibre technology, down is still the best insulator warmth for weight, and is also the most durable sleeping bag insulation.
- The problem with down is its vulnerability to water; moisture decreases the ability of the down to loft to its full potential and insulate, decreasing the warmth of your sleeping bag. Once down is damp or wet, it also takes a long time for it to dry out and effectively insulate again.
- With the introduction of water-repellent ULTRA-DRY Down™ we have virtually eliminated the negative effects that moisture has on down. The ULTRA-DRY Down™ water-repellent treatment protects the down from external moisture and internal condensation.
- ULTRA-DRY Down™ is a permanent* Nano-level water repellent polymer treatment applied to our high loft, high quality down. The Nano-thin treatment vastly improves our 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.
- Sea to Summit sleeping bags, using ULTRA-DRY Down™ in combination with our already formidable 2D- and 3D-NanoShell™ system give you the best chance of sleeping warm and dry, day in day out throughout the worst of conditions. With these technologies combined there is simply no reason to choose any other insulation or shell for your sleeping bag.
