LK-70 is an old classic bergen made for war!
Generations of swedish soldiers have used them
for months at a time in the wilderness. They are rugged, heavy and lacks all luxery, but will never
let you down. The size is perfect and you can carry anything with that frame.
Some of them have been around for forty years now, so there is a small risk of the waterproofing
layer on the inside of the snow lock having dried up and comming loose from the fabric. (The thinner
fabric that is.) If so, you'll have to brush it off and apply new waterproofing, if you want to.
Not neccessary, easy to do and you can use whatever type you want.
The rucksack even has ski channels behind the side pockets!
Only the old US Alice packs comes close to this quality/price, but the LK-70 has a much
better balance, which gets important on long expeditions.
If you use it extensivly you might end up loving it.
The LK-100 is much newer and might be one of the worlds best backpacks, which
is also reflected in it's price. It is used by the Artic Ranger Regiment in Arvidsjaur

A sadly soundless clip that shows what conditions these packs were designed for:
