Watching the northern lights is mostly waiting. You stand in the snow, you look up, and you stand some more. Being a little cold for ten minutes is fine. Being cold for three hours ruins the night, even if the sky is putting on a show. The trick is simple and very Norwegian: layers, wool, and nothing made of cotton.

layers, from wool next to your skin to a windproof shell
pairs of wool socks, so buy boots with room for both
The short answer
Wool inside, windproof outside, and nothing made of cotton.
Cotton holds on to sweat and stays wet, and wet is cold. That's why everyone up here wears wool next to the skin. That one swap makes more difference than the most expensive jacket.
Before you buy a big suit for one trip, check your tour. Many operators lend thermal suits, boots, hats and mittens, so you may only need the layers underneath.
Dressing, from the skin out
Three layers, plus the bits that get cold first. It works because you can add or take off a layer when you go from a warm bus to a cold field and back.
-
Wool next to your skin
Long-sleeved top and long johnsLayer 1Thermal underwear in wool, top and bottom. Wool socks too. This is the layer that matters most, and the one tour operators don't lend you.
-
Something warm in the middle
Wool or fleeceLayer 2A wool or fleece sweater and trousers. On a very cold night, add another one. It's easier to take a layer off than to wish you had one.
-
A windproof shell
Jacket and trousersLayer 3A jacket and trousers that keep out wind and wet snow. If your tour lends a thermal suit, this is what it replaces.
-
Hands, feet and head
The bits that go firstDon't skip theseWarm boots with room for two pairs of wool socks, mittens or warm gloves, a hat and a scarf. Heat packs inside your gloves and boots help on long nights. Grips or spikes on your boots stop you sliding on icy pavements, and you can buy them in sports shops and at the tourist information.

All northern lights placesPractical tips
- Put the layers on before you leave the hotel. Changing in a cold minibus is nobody's idea of fun.
- Keep your phone in an inside pocket. Cold drains the battery fast.
- Bring a thermos if your tour doesn't include hot drinks.
- Tight boots make cold feet. Leave room for the second pair of socks.
