You can save a lot of weight by choosing your ‘big three’ wisely: rucksack, sleeping bag and tent.
Burton AK 55L rucksack.
It did weigh 1850g, but I cut off everything I could, so it’s now 1080g with the frame. Claudia uses a Lowe 25L rucksack with no frame (600g).
Western Mountaineering SummerLite down sleeping bag.
Rated to 0°C.
Helsport Reinsfjell Superlight 2 tent.
Though slightly heavier, I think it’s much better than the super, super-light one which has only a mesh inner. As the temperature may drop below -7°C north of the Arctic Circle in summer, the air current though the mesh is no fun. So I prefer two walls.
It also has more space. If you’re walking in the rain for days you’ll want to cook inside and keep all your stuff there without always moving it around stuff. Also, I am 190cm and a lot of tents are so short you’re touching the wall with your foot - and then if it rains you get wet etc.
I also like that the fly sheet goes down all the way to the ground. European tent brands such as Helsport, Terra Nova and Hilleberg are designed for camping in rainy, windy and swampy places like Scotland and Scandanavia. A lot of US tent brands are designed with dry, desert conditions in mind, with more venting - so bear that in mind when you’re choosing your tent.
Gas stove for cooking.
Have a trial run at home to test how much you need each day. Figure out exactly how much gas you need to boil a litre of water from snow, lake or creeks.
In warm weather, we boil water three times each day. Oxtail soup for lunch (replaces the salt you lose while walking), dehydrated food for dinner and tea at night.
Over a week we’ll use a 250g bottle, though it can be less if we make fires. If it’s cold, you’ll need more. Often at the very start of a trail there are nearly full, leftover gas bottles which people leave because you can’t take it to the plane.
A wind shield for your stove
Saves more in fuel than you lose in the extra carrying weight you carry, especially for longer trips.

Titanium is lighter, but takes more heat and therefore gas, so you lose in the long run!
