Fjord Nansen Bivak Sleeping Bag Sapphire 1150 g - left
Durable sleeping bag in Sapphire color, featuring a rectangular envelope shape that ensures a comfortable position and freedom of movement during sleep. Made from tough Rip-Stop polyester, it has a resistant outer shell and synthetic Eko Loft Hollowfiber insulation.
Temperature and usage conditions
The usage temperatures of the Bivak sleeping bag are defined in accordance with EN 13537 standard:
- T-comfort: 13 C – the lowest temperature at which a woman can sleep comfortably through the night,
- T-limit: 8 C – the lowest temperature at which a man can sleep through the night without discomfort,
- T-extreme: -3 C – the lowest temperature one can survive in the sleeping bag. Not recommended for regular use.
Rip-Stop reinforced polyester, PoliCotton lining
The outer layer made of 210T Rip-Stop polyester effectively protects against abrasions and damage, and prevents further tearing. The interior is finished with PoliCotton, combining the softness of cotton with the strength of polyester, offering a pleasant feel and proper ventilation. Inside, there's a functional pocket for valuable small items.
Eko Loft Hollowfiber filling
Thermal insulation is provided by Eko Loft Hollowfiber synthetic filling made from spirally twisted, siliconized polyester fibers. Quilted outer fabrics ensure even distribution of insulation. The padding retains its properties even after getting wet, frequent washing or heavy use. The filling does not cause allergic reactions, making it suitable for those allergic to down.
Left-sided zipper, Anti-Bite system, DUO drawstring
The two-way zipper on the left side allows unzipping from the top and bottom, making it easier to get in and out. The Anti-Bite system prevents fabric from getting caught in the zipper, while the internal thermal baffle enhances heat retention. The DUO drawcord – a combination of elastic and webbing – enables easy adjustment around the neck and quick loosening when needed, especially during night activity. This model can be connected with another sleeping bag from the same series.
Convenient transport and storage
Easy to carry and store – when packed, it measures 37 x 21 cm, and compresses down to 22 x 22 cm. Weighing only 1150 g, it doesn't add much to your luggage load.
Set contents
The set includes a compression sack with buckle closures, protecting the sleeping bag from dirt and damage during transport.

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.
Eko Loft Hollowfiber is a synthetic insulation material used in sleeping bags. It consists of spirally twisted, siliconized polyester fibers of various diameters, which form a system of microchannels filled with air. Thanks to this structure, the filling is warm, resilient and easy to compress. It retains its insulating properties even in a humid environment – it does not absorb moisture, and at the same time allows the removal of water vapor produced by the body. This material provides thermal comfort at low temperatures and is also anti-allergenic.
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.
