Fjord Nansen Svalbard 680 Duck Hydro XL Sleeping Bag 1070 g - right

Ultralight mummy-style sleeping bag designed for ergonomic body alignment and maximum freedom of movement throughout the night. Crafted from premium nylon, this model combines a robust outer shell with a duck down insulation for optimal comfort and durability.

Temperature ratings and usage conditions

Waterproof map case in A4 format, constructed from robust TPU plastic with a 0.3 mm thickness and an outer layer of PU. The case features a roll top closure for secure sealing. The chosen materials are highly durable and provide resistance to UV radiation as well as low temperatures (as low as -20 deg. C), while also meeting the IPX7 waterproof rating (protection against submersion in water for up to 30 minutes at depths of up to 1 meter).

Double-sided transparent construction is touchscreen-compatible, allowing use not just for shielding maps from water, dust, and other potentially damaging conditions in the field, but also offering protection for smartphones, tablets, and other accessories.

Set includes an adjustable carrying strap made of 3 mm thick paracord with reflective elements for easier transport.

10D Rip-Stop nylon with Water Repellent coating

Constructed from lightweight 10D nylon featuring a Rip-Stop weave and coated with a hydrophobic WR layer on both the exterior and interior, the material minimizes moisture absorption. The inner section incorporates a small pocket for valuables, as well as attachment loops for securing an extra thermal liner.

Duck down filling, H-shaped construction

Optimal thermal insulation and efficient air circulation are provided by a European duck down and feather fill in a 92/8 ratio. Featuring down with a loft of 800 cuin and high compressibility, the sleeping bag can be compactly packed for transport. A hydrophobic coating shields the filling from moisture. Utilization of an H-shaped baffle system ensures the down remains evenly distributed and avoids clumping. Designed with a footbox shaped like a shark fin, the structure aligns with the natural foot position during sleep, maximizing thermal efficiency and freedom of movement, while minimizing pressure to promote sleep quality. The sleeping bag’s base is constructed with a 70-degree angled seam.

Right-side zipper, Anti-Bite system

A two-way zipper positioned on the right side enables full access from either the top or bottom, ensuring rapid entry or exit. The zipper is equipped with a fluorescent puller for effortless location in low-light conditions. The integrated Anti-Bite system safeguards the fabric against snagging. A thermal baffle inside provides additional protection along the zipper. 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 maximizes thermal efficiency by fully covering the head and limiting heat escape in cold environments. The contoured shape provides superior defense against wind and damp conditions. The DUO drawcord system integrates both elastic and webbing elements; elastic at the neck permits unrestricted hand movement without continual adjustment, while the rear webbing enables rapid loosening in key zones—an essential benefit for nighttime use. An internal thermal collar, constructed as a down-filled tube complete with a drawcord at shoulder level, effectively prevents the infiltration of cold air into the sleeping bag, delivering optimum performance in low temperatures.

Convenient transport and storage

Designed for portability and convenience, this model is compact and lightweight, with a packed size of 36 x 19 cm and a total weight of just 1070 g. Easily fits into your gear without adding unnecessary bulk.

Kit components

Supplied with a durable compression sack, ensuring the sleeping bag remains protected from dirt and damage during transportation.
