Be prepared for rain, snow and wind! Wear waterproof clothes and shoes and have warm clothes and some change in your backpack. Bring sunglasses, snow is brighter than you expect in sunny weather. Do not underestimate the need for proper equipment, and don’t leave in sneakers!
If you do not have good enough equipment, NTNUI Bumerang rents out equipment to NTNUI members for free! (supply is limited)
Wool has the function that it contains a lot of air. This air will work as insulation and will keep you warm and at the same time it transports the sweat away from your skin. Due to this, wool will keep you dry and warm, even in wet condition. Fleece is not as warm as wool, but is a far warmer fabric than cotton, which is totally unsuited for use in the mountains.
In windy conditions (very common in the mountains), a jacket with a windproof hood is recommended (30% of the body heat is lost by the head and neck).
In March/April/May the mountain sun is very strong due to reflections from the snow. Use a sun lotion with factor (at least) 10 and sunglasses that cover your eyes well.
It's better to undress some garments if you feel too warm. A warm body produces sweat and water leads cold eight times better than air. Walk 10-15min and then decide whether to undress or not.
Drinking water for your stay at the cabin don't need to be carried in the backpack since it can be found nearby all cabins, in small streams, rivers or lakes. During winter, it is often worth the effort to dig a big hole in the snow down to water sources. Especially when you are a big group, it is hard to get enough water from just melting snow. If you end up with the latter solution, always keep a pot with snow on the stove, since it will be warm due to heating anyhow.
Put clothes, sleeping bag, toilet paper, matches, camera etc. in plastic bags so they don't get wet. The sleeping bag should be sufficient to sleep below 0°C.
Your drinking water may freeze. Keep it inside your jacket, close to your body, or use a thermos bottle. Remember to drink at intervals while walking. When you walk you sweat, but in wintertime you don't feel it the same way as in summertime because of the cold. You can never drink enough! Some plaster, gas bind and sports tape is recommended. Fat crème with a small density of water is good as protection against dry hands and cold. Ask at Apoteket.
You don't need to bring all types of ski waxes. A couple is often enough. The waxing zone on skies is from your heel and 40-50cm forward.
Keep batteries warm. A cold battery doesn't work well. Bring extras with you.
The primus stoves at all cabins use about 3dl paraffin (more for larger groups) and less than 1dl Rød-sprit a day (cooking morning and evening). Bring some extra paraffin for the paraffin lamps. Check the primus instructions to get to know how a primus works before you leave!
Real candles give much more light (and less waste) than tea candles.
If you have to dig yourself into the snow (remember that break-ins into cabins nearby is not allowed!), you will need a snow spade. It might sound extreme, but the mountain does not show any respect. Inside the snow you will be able to maintain temperatures above 0°C.

Backpacks, which you buy today, have a lot of possibilities for adjustment to your body. Read the user manual for your backpack or ask the salesmen before you use a new backpack for the first time. There are some general tricks you can do to make your backpack more comfortable to carry.
Only a few cabins are accessible directly by roads or paths. To all the others you need proper and waterproof footwear with a robust sole. Only shows with a sufficient height made in leather and/or with a Gore-Tex membrane will keep your feet dry during the trip. Wet shoes will quickly get cold and normally won't dry over night in a cabin.
Ski boots of leather or soft plastic is to prefer for longer walks. Hard plastic boots (for downhill skiing etc.) might be uncomfortable after some kilometres, and are not recommended for cabin trips! Snowshoes might be comfortable when you are climbing in steep terrain, but for longer walks in high snow with a heavy backpack it's not recommended. However, if skis are a No-Go for you, snowshoes are still much better than leaving without any winter equipment!
In Norway, the following ski types are common: Langrenn (cross-country), Turski (back-country), Fjellski (mountain) and Telemark (telemark). In principle, you should avoid cross-country skis since those are too thin for soft snow and have no steel edge. On the other side, wide telemark skis are often too heavy and not comfortable on the way to the cabin. However, these types are still much better than going without skis, which is definitely not recommended!
