Temperature ratings and usage conditions
The operating temperatures of the Svalbard sleeping bag are specified in accordance with EN 13537:
- T-comfort: 0 deg C - the lowest temperature at which a woman can comfortably sleep through the whole night,
- T-limit: -6 deg C - the minimum temperature at which a man can sleep through the night without discomfort,
- T-extreme: -24 deg C - the lowest temperature at which it is possible to survive in the sleeping bag. This is not a value recommended for standard use.
10D Rip-Stop nylon with Water Repellent coating
Both the exterior and interior feature lightweight 10D nylon with Rip-Stop weave and a hydrophobic WR coating, ensuring enhanced resistance to moisture. The material treatment helps prevent water absorption. The interior includes a small pocket for essential items and loops designed for attaching an additional thermal liner.
Duck down filling, H-shaped construction
Superior thermal insulation and optimal air circulation are delivered by a filling of European duck down and feather blend in a 92/8 ratio. Featuring a loft of 800 cuin and exceptional compressibility, the down allows the sleeping bag to be packed down to a compact size. A hydrophobic coating offers reliable protection against moisture. The H-shaped baffle design prevents down from migrating and forming cold spots. An anatomically shaped shark-fin footbox aligns with the natural position of the feet while sleeping, maximizing thermal comfort, boosting freedom of movement, and minimizing pressure to improve overall sleep quality. The base of the sleeping bag is sewn at a 70-degree angle.
Left-side zipper, Anti-Bite system
Fitted with a two-way zipper along the left side, enabling complete opening from either the top or bottom for fast access or exit. A fluorescent puller ensures quick zipper location even in low light conditions. The integrated Anti-Bite system protects the fabric from snagging. Internally, a thermal baffle reinforces the zipper insulation. Compatible for connection with another sleeping bag from the same series.
Integrated hood, DUO drawcord, thermal collar
Featuring a built-in 3D hood, the design improves thermal efficiency by surrounding the head and minimizing heat loss in cold environments. Its structured form boosts protection against wind and moisture. The integrated DUO drawcord utilizes both elastic and webbing components: elastic at the neck permits unrestricted hand movement without the need for adjustment, while the rear webbing allows for rapid loosening in specific zones—particularly advantageous during nighttime missions. Incorporated inside, the thermal collar—a down-insulated tube equipped with a drawcord at shoulder height—prevents the infiltration of cold air into the bag, delivering high performance in low-temperature conditions.
Convenient transport and storage
Designed for convenience, this model is highly portable and compact. Packed dimensions are 36 x 19 cm with a weight of just 825 g, making it easy to transport without adding unnecessary bulk to your load.
Set elements
Equipped with a durable cover, the sleeping bag remains shielded during transport, safeguarding it from dirt and potential damage.

Rip-Stop weave protects the fabric from abrasions and tears. It is characterized by additional threads woven in at regular intervals, forming a mesh-like pattern. It provides high strength to the fabric, increases resistance to mechanical damage, especially tears.
Anti-Bite is a system that prevents material from getting jammed in the zipper, used in outdoor clothing and equipment. It prevents the fabric from blocking the zipper, which increases the durability of the product and improves the comfort of use, especially in outdoor conditions.
DUO drawstring in Fjord Nansen sleeping bags is a two-zone adjustment system, which allows you to adjust the hood independently with an elastic band in front and a tape with a lock in the back. This solution makes it easy to quickly adjust the sleeping bag to your body position and personal preferences, without having to leave the interior.
