Sea To Summit Treeline TII Sleeping Bag

Our Treeline™ Sleeping Bag is a budget down bag that is ideal for three season use when you’re confident the temperature won’t drop below freezing. While we’ve given this design a little extra room around the shoulders and hips for freedom of movement, the relaxed mummy shape still provides efficient warmth and heat retention when you need it. Filled with 400g of compressible and lofty 600+ down, the Treeline™ will keep you warm and comfortable. The two-way YKK #5 side zip with anti-snag fabric provides easy access and ventilation for warmer weather.
Utilising our unique internal cord tunnel in the hood and neck draft tube, the Treeline™’s exterior finish is kept neat and free of additional loose fabric. The internal chest pocket is a great spot for keeping valuables secure, or batteries warm. The 50D Nylon shell and lining fabrics provide long-term durability while still offering good compressibility. Light enough for backpacking adventures, this sleeping bag can withstand the rigours of sharing your outdoor adventures with kids or dogs.

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.

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.

650+ 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.
- 650+ Loft Premium Down: In the Sea to Summit Trek range, 650+Fill Power Premium duck down is a high quality insulation that sets the benchmark for sleeping bags in this class.
