The role of the Svalbard in Helsport’s range is essential and very simple: it is our warmest down-filled sleeping bag. We combined our experience in designing equipment for the most extreme environments on earth, all we learned from the fit and fill technology from our Rago range, and took it to the next level. Only the hybrid Spitsbergen is warmer and gives more protection in extreme cold.


The pattern and specifications for the Svalbard allow full loft from the premium 90/10 800 FP goose down, maximising warmth and reducing the chance of cold spots forming at pressure points. We calculated the thickness of loft we would need and carefully adjusted the fill, patterns and baffle shape so that the bag actually lofts gently inwards to rest comfortably against you, giving a luxurious night’s sleep.



The lining fabric is the same premium-quality 30D Pertex taffeta used in our Rago series and the shell is a light but durable Pertex mini-ripstop, treated inside with an additional 1000mm water-resistant breathable coating. Both of the fabrics have C6 WR treatment.
