The version with an insulated hood was very shortlived, as far as i know. It quickly got replaced with the one with a thin roll-up hood. There was a story about a visiting general snuck up on a soldier on guard duty (with the hood up)...I don't know if there is any truth to that really, but we got re-issued quickly, though.
I have checked Swedish web stores, but without any luck
Happy hunting!
