Finland's Varusteleka sells a multipurpose "Jerven Fjellduken" tarpaulin that you're meant to wear, sleep under, and sleep in. It makes you look like a well-camouflaged Nordic Nazgul.
Jerven bag, those are almost words of power among hunters, outdoorsmen and soldiers the world over. Jerven has been making the Fjellduken since 1982, besides the obvious hunting trips and hikes the Fjellduken has seen action in Afghanistan in the hands of Norwegian and Danish special forces.
You won't find any hi-fi bullshit in your Jerven bag, the technical bits start and end at the zippers, that's it. All of Jervens products are made and developed by the very same people who use them. The unique design and materials make the Jerven bag an incredibly versatile and high performing piece of equipment. This is not your standard modern trinket, which relies on never ending lists of one after another more trivial properties and features to impress people, this is simple perfection at its best!
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
