Blackjacket in the cold?

I want to upgrade my black T-shirt darkcloth for something better and like the look of the Blackjackets. I will use it with my Norma monorail in 4x5 mode, but I have a 5x7 conversion too, so I plan to get a 5x7 size to keep my options open. I am trying to decide between the original version and the hybrid, breathable model.

I am particularly interested in any differences between the two models in the sort of hovering-around-freezing, claggy weather I always encounter in Scotland, and the colder (-10°C to -30°C), snowy conditions of the Nordic winter. I am especially interested to know if the breathable hybrid helps to prevent moisture buildup and frost inside the cloth. Keith at Quietworks has given me some useful tips, but I would value user reports from those in colder climes.

Sheeesh! In that cold of weather, I would want a darkcloth that was heat insulated to hold in my body heat when I am under it! I could see how moisture buildup on the ground gas could be a problem thought, I have had to deal with that before. When I used to scuba-dive, I would clean my mask with toothpaste, then wash it off...and that would prevent it from fogging up. Maybe you could do something similar with your GG? I know they make antifog glass cleaner as well.

Tim Atherton who posts over on the lfphoto.info forum uses his in northern Canada in real colddd.d.d.d.d.d weather. I'm sure he can provide comparisons as, IIRC, he has used both versions.


Bob.

Thanks for the answers. I've emailed Tim Atherton to see what he says.

-30°C (NB centigrade) is about the point where I stop having fun. I've camped, climbed and gone ski-touring at those temperatures, but the incentive has to be that much larger than if it's a balmy -20°C or so. Naturally, it's the really cold days that often have the best light.
