Housil:
the norwegian army bags i have are made by synthetic fibers
not down.
down bags are mostly used when you go to the north pole where you have extreme cold weather
al the time and its real dry cold clima.
these bags is supose to handle both dry cold and moist weather, since its only
ranger bag that have a water proof outerliner the others can be changed with the supply
if real wet. the norwegian army dont supply water p liners for al their bags since they cut down
money on the gear so we use other nations liners when we are on exersices
i have used al the types execpt the 2000model and i like them pretty good,but i preffer
the ranger bag with the outside liner and extra ground mat.
the other bag in the picture with the ranger bag is also a winner so far
but it dont have the wet liner so you have to add a us made or other
goretex liner.
i have used them in minus35-celsius without any freezing,but we use wool clothing on
the body when we go to sleep since the norwegian army says we have to by law
they dont want any law suits afther an exersice for frostbites and other cold weather injuries
when it got extreme cold when on exersices i used to go to the medi vac people and borrow a pasient
body heater

to put in the sleeping bag.
we never use to sleep with the boots in the s bags,thats a no go from the army
when red alert we used to sleep in full combat gear with the bags on topp of us like a blanket
the things we used to dry in the bags was wool socks.
