    Svalbard

    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.

    To give additional warmth around the head and shoulders, we reshaped and enlarged the internal collar and the hood, adding extra down for even more loft. The baffle design around the shoulders has been adjusted to keep the down in place, where it’s needed. The main zip is shortened to three-quarter length and has a large down-filled baffle to increase warmth.

    One area in sleeping bag design that deserves special attention is around the feet. It’s only too easy to push against the end of the tent, compressing the bag and reducing warmth, as well as getting the down wet. To overcome this we have added a layer of recycled synthetic fill to the foot box to resist compression and maintain the bag shape, therefore increasing loft. Synthetic fill will also perform better if any moisture does get inside the bag.

    Because we are always thinking of our environmental footprint, we selected a recycled synthetic fill that nonetheless meets our demanding standards of thermal efficiency.

    The Svalbard looks huge on the outside and is a lot of sleeping bag. It’s size is a result of the almost 11cm of loft needed to keep you warm at -40 degrees but even so, we have achieved this level of performance in a sleeping bag that weighs less than 2kg. It is essential expedition equipment.

      1. What's the european temperature rating?

        Since 2012 Helsport has used the European standard EN13537 to rate its
        sleeping bags. This standard allows comparisons amongst sleeping bags from
        different producers.

      2. What does the temperature values: TCOMF, TLIM and TEXT mean?

        It is important to know that the temperature rating is valid for an average
        person, in an average situation. When you are out hiking, no single trip is the
        same. People react differently to cold, levels of fitness can vary, and the
        surroundings will change every time.

        • TCOMF: the green zone is called the "comfort zone", and in this
          temperature range most people will be able to sleep comfortably.
        • TLIM: the yellow zone is called a "transition zone", between comfort and
          risk. Many people can sleep comfortably in this temperature range, but
          some may also start to freeze.
        • TEXT: The red zone is the "risk zone" and, in this range, a strong
          sensation of cold has to be expected. There is a risk of hypothermia. An
          average-sized woman can only tolerate this zone for six hours.
      3. Synthetic or down?

        There are no hard and fast rules here, and what type of sleeping bag is right for
        you will depend on what type of trips you’ll be using it for, your personal
        preference and your budget.

         

        High-quality down sleeping bags will always be warmer relative to their weight
        than synthetic sleeping bags. The lifespan of the two types is roughly the
        same. Down sleeping bags are more demanding with regard to correct
        maintenance and storage (they should be stored in the storage bag or hung
        up).

         

        Synthetic bags insulate better than down bags when wet. Luckily, it’s rare for a
        sleeping bag to get soaking wet, but it’s something that’s worth bearing in
        mind when choosing a sleeping bag. Regardless of how well a sleeping bag
        insulates, it’s no fun sleeping in a wet bag.

      4. Can I wash my sleeping bag?

        You certainly can wash your sleeping bag, but you shouldn’t do it too often.
        Using a sleeping bag liner that can be washed often is a good alternative.
        A sleeping bag liner does not only protect your sleeping bag, it’s also very
        comfortable and can increase the temperature limit of your sleeping bag by
        up to 8 degrees.

        Sleeping bags can be washed at 40 °C with a low spin. It’s important to use a
        detergent especially adapted for sleeping bags in order to avoid residue
        building up in the filling. Synthetic sleeping bags can be washed at 60 °C,
        although this will shorten the product’s lifespan. Again, we recommend using
        a liner instead and washing it more frequently if required.

        Always tumble-dry your sleeping bag. It’s a good idea to put some tennis balls
        or special dryer balls in the drum to help “fluff up” the bag’s filling again.

      RDS - Responsible Down Standard

      All Helsport down sleeping bags use only down which is certified according to the Responsible Down Standard. 

      The Responsible Down Standard aims to ensure that down and feathers come from animals that have not been subjected to an unnecessary harm, and at the same time, provide retailers and consumers with greater confidence in responsible sourcing. RDS certified down is a by-product from the food industry, and are not plucked from live birds.

      The goal of the Responsible Down Standard is to ensure that the water fowl in the down supply chain are treated humanely. RDS requires independent, third-party assesments of all aspects of animal rearing and handling throughout the entire supply chain.
