Step 1: Deciding the weight of your duvet

The first step in the process of choosing your down duvet, is to decide on the weight of the filling. Three important factors to consider are:

  1. The typical climate of your location
  2. How the temperature in your bedroom changes with the seasons
  3. Your personal temperature preferences

Our duvets come in the following varieties:

  • Summer duvets

    An airy, lightweight duvet, making even the hottest nights dry and comfortable. It is filled with small amounts of down, spread over many channels to create an almost see-through duvet. Also good for bedrooms with air conditioning.

  • All year duvets

    A versatile down duvet for rooms and environments that keep a relatively even temperature through the year, as well as bedrooms with air conditioning.

  • Winter duvets

    Soft and comfortable, this duvet will keep you perfectly warm in cold rooms and temperatures. Also ideal for those who like to keep your windows open during the winter.

  • Polar duvets

    Well filled with wide channels, these ultra-warm are designed for cold winters in cold climates, as well as sleepers who feel the chill easily. When the weather outside is frightful, you will be perfectly cosy under your duvet.


A lot of duvet manufacturers use the term “TOG” to explain how warm their duvets are. In our experience, this reference proves confusing to many customers.

So, here is a brief explanation: the better the down quality, the bigger the down pearls. The larger the pearls, the less down that is needed inside, resulting in a product with a low weight. The lighter the duvet, the more air can circulate inside it – and the more air inside the duvet, the better the duvet is at regulating the temperature.

As Norvegr duvets contain distinctly high-quality down, they are also very light, meaning one of our duvets will keep you warm in cold temperatures while also keeping you cool in higher temperatures. In TOG terms, this is contradictory.


Rather than confusing you with the term TOG, we instead offer our own guidelines. Of course, you should still consider your own personal needs and preferences when choosing your duvet – and you are always welcome to contact us should you need advice.

  • Polar duvets

    When the outside temperature has dropped to as little as -20°C/-4°F and you keep your bedroom windows open at night these duvets will keep you warm all night. The bedroom temperature might drop well below 0°C/32°F but you will keep toasty and warm still. These are the warmest duvets we make, and they are made for climates where it is particularly cold. They are also the right choice for those that generate little body warmth during the night and get cold very easily. If you keep a glass of water on your bedside table, the surface might freeze to ice while you are still keeping snug and warm underneath your polar duvet. When the weather is warmer, polar duvets are suitable in temperatures as high as 10°C/50°F inside the bedroom.

  • Winter duvets

    If you live in a climate where there is a significant difference between summer and winter temperatures, this is the ideal duvet if you prefer to keep your bedroom windows open at night. Addtionally, if you get cold easily at night, this is a nice duvet to use during the winter even if you prefer to keep your bedroom window closed at night.  When the outside temperature outside has dropped to as little as -10°C/14°F and your bedroom temperature drops towards 0°C/32°F, these duvets will still work well. At colder temperatures, we would recommend using a blanket over the top of the duvet or choosing a Polar duvet. Winter duvets are suitable for bedroom temperatures as high as 10°C/50°F.

  • All year duvets

    If you prefer to keep your bedroom windows closed at night and the temperature inside your bedroom is relatively stable at most times, this is the ideal duvet for you all year through. It is a wonderful option for well insulated houses and apartments or for those bedrooms where heating and/air conditioning keep the temperature stable. When the outside temperature outside has dropped to as little as 0°C/32°F and your bedroom temperature drops well below 10°C/50°F, these duvets will still work well. At colder temperatures, we would recommend using a blanket over the top of the duvet or choosing a Winter or Polar duvet. All-Year duvets are suitable for bedroom temperatures up to 20°C/68°F.

  • Summer duvets

    If the summers are warm where you live, or if it is warm all year through, these are the ideal duvets for you. Furthermore, if all that is mentioned under all year duvets above is valid for your bedroom, but you feel that you easily get warm during the night, this is the duvet you should choose. When the bedroom temperature is dropping towards 5°C, these duvets will still work well. At colder temperatures, we would recommend using a blanket over the top of the duvet or choosing an All-Year duvet. Summer duvets are suitable for bedroom temperatures as high as 25°C/77°F.

  • Custom made duvets

    Sharing your bed with a partner who wants a different duvet weight to you? No problem: we can create a double duvet with different weights to suit you both. Please call or email us to find out more.

Adjusting your duvet to your needs

Over half of our customers choose the versatile All-Year duvet. However, if you are someone who gets cold easily, or if your typical outdoor temperatures shift above or below the All-Year duvet parameters during the course of the year, we would recommend purchasing a Summer duvet and a Winter duvet to keep you comfortable throughout each season. Additionally, if you are a sleeper prone to overheating, or you live in a hot climate, you might find that you are happier with a Summer duvet rather than an All-Year variety.

As a part of our service, we will gladly adjust your duvet if you find it too warm (or not warm enough). If you send the product back to us we will not charge for this service, but if you want us to fill more down we need to charge for the material. Alternatively, of you want us to take down out, this cannot be resold and will either have to be thrown away or we can use this towards filling pillows for you. As Norvegr products are designed to use for years, it is important to us that any duvet and/or pillow you choose is just right for you. The shipping back to you when the adjustment is done is therefore on us.

Step 2: Deciding your duvet size

We always recommend a 220cm/87" length of the duvet, or longer. Don’t worry about choosing a duvet that is considerably larger than your bed, as any excess width and length disappears when you wrap the duvet around yourself – and if there are two of you, it’s nice not having to fight for the duvet.

Step 3 – Choosing the quality of down for your duvet

All our duvets are made with pure, 100 % down – never feathers. Our down is also of the very best quality and has to pass a rigorous quality control test before being used.

Fill power/loft

Fill power is the international measurement for down’s capacity to retain air. This is measured on a scale from 1 to 15cm according to European norms – or, according to the International Down and Feather Bureau, on a scale from 0 – 225 mm or 0 – 900 CUIN, which is often referred to as “loft”.

The fluffier and less compressed the down mix is, the better the quality of your comforter. The greater the fill power, the lower the weight of your duvet. This allows for more air both inside the duvet and between the duvet and your body, meaning moisture can escape and the air around you can be regulated to body temperature effectively.

  • Arctic White Duck & Goose down mix (Standard Collection)

    100 % down - Fill power 11cm/155 mm/625 loft

    This beautiful white mix of duck and goose down, 100% down is very light. We use it in the full range of Norvegr Standard Collection down comforters and our luxuriously soft Classic Collection pillows. This down delivers the unique experience of a 100 % down filling and provides good insulation, moisture transportation and temperature regulation simultaneously.

  • Arctic White Goose (Classic Collection)

    100 % down - Fill power 12cm/170 mm/705 loft

    Sea birds living in the Arctic develop ultra-warm down to cope with sub-zero temperatures. Snowy white down from the Arctic White Goose feels almost weightless yet keeps the body at the ideal sleeping temperature. This down quality copes with cold winters as well as hot summers, creating a supremely comfortable personal micro-climate. The simultaneous insulation, moisture transportation and temperature regulation from the Arctic White Goose down is excellent.

  • Siberian White Snowgoose Altai (Premium Collection)

    100 % down - Fill power 14+ cm/210 mm/850 loft

    This natural product is renowned worldwide for its outstanding insulation and fill power, making for an unbeatably warm yet extremely light duvet. The goose survives the Siberian winter in extreme temperatures of -40°C/-40°F thanks to the remarkable quality of its down, which produces the best loft (aka fluffiness) ever measured, making Siberian White Snow Goose the best commercially available grade of goose down in the world. All at once, this quality of down insulates, transports moisture and regulates temperature in an unsurpassed way.

  • Norwegian eiderdown from Svalbard (Limited Edition)

    Limited to an annual quantity of less than 100kg, eiderdown sourced from the Norwegian island of Svalbard is one of the rarest and most exclusive qualities in the world. It takes experts at least a week to hand-clean just one kilogram of pure eiderdown without feathers, and approximately 60 nests to yield enough raw material to fill one regular duvet. By hand-cleaning the eiderdown, its superb qualities are preserved, making for the ultimate comforter. This material was sought after by kings and queens back in the Viking Ages, and it is to this date still the absolute best material in the world for duvet making. It has the best heat retention of all materials in nature.
