I have used/own several Jerven "tarps", and would say that I have yet to see/try anything simular that is as good.

They are high quality products, and used by both hunters and many military units here in Norway.

Interesting Do they live up to the promises? Which models have you used?

Will they fully replace the rain gear?

Please, feel free to elaborate

Cheers

Johan,

I have used the following models:
"Orginal"
"Termo King-size"
"Termo-Extreme"

Here's a picture of my wife having a midday nap in a "Orginal":


As for if they will fully replace rain gear, I personally would say no. This is because I have never been a fan of ponchos (which the Jerven can be used as).

I imagine that I would become quite wet after having spent a midday nap in one of those. As far as I understand there are no model with a goretex membrane or any other breathing membrane. The liner in the "Thermo" version is said to "eliminate" this problem. I believe that "postpone" is a better word for it.

Has condense caused you any problems so far?

Have you been able to find any weak spots or durability problems?

Olli,

If it was warm, then you would most likely get damp due to sweating. But if it's cool as it was when I took the above picture(around 5 degrees celcius), it wouldn't be as big a problem. I think the thought behind the sacks material is that it's better to be a little damp after a while, then be soaking wet, or freezing to death due to outside conditions because you don't have one.

Your thoughts of the interiour "thermo" material postponing getting damp would be correct IMO, as the Jerven are indeed not made out of breathing materials, but the "thermo" part sucks it up. I haven't experianced (nor heard of) this being a big problem. And I've used them both in rain, sun and snow. I have friends who have used the Thermo-extreme as sleeping bags overnight (with nothing else) in sub zero conditions, and have felt this worked fine too (granted, they were in uniform, and didn't have much of a choice!).

As for duability, they seem to last and last. The cloth material is tough, as are the heavy duty zippers.

Ok.

Gear that have been tested by military personnel usually also meet the needs for most of us. Even though comfort isn't always regarded an important feature.

Reasonable prizing too.

Bought a Thermo a couple years ago - can confirm everything that ErikD has said.

Mine has been used as a sleeping bag cover in -25 as well as frequently on high seats/deer stands when there are high winds/low temperatures.

The heat that you build up in a Fjellduken is quite amazing - and whilst I have never noticed condensation problems, the material is a little noisy. Not sure I would use it as a hiking waterproof - but as a microclimate in adverse conditions - its a winner!!
