An old idea re-vamped???
I recently saw the adverts for Pertex shield jackets by Rab and Montane. Always on the look out for new breathable fabrics I happened to see some last week in Betws-y-Coed. The lightest I saw was a Montane weighing in at a paltry 215g (£140). Trying it on was like putting on a jacket made of paper, I was convinced it was going to tear.
Next up was a heavier Montane jacket at 325g. I was told the difference was the lighter one used a PU laminate which made it lighter and more breathable. The heavier one used a PU coating which made it tougher heavier and less breathable. (£100).
Then there was one from Rab at over 300g with an enormous hood suitbale for a helmet. (£150). Finaly I found one made by OR which weighed 14oz. and cost £200. I liked the chest pockets on this one as they were above waist belt height. All four had floppy hoods.
Now the thing is I have a pair of Mardale overtrousers that are about 13 years old made of Pertex with some kind of laminate over them to keep out the water. True it might not be a PU laminate and they're not exactly featherweight. So is this really a new idea? Or a re-vamp of an old one?
So what about my Mardale overtrousers? Well they've hardly been worn over that 13 years, spending most of their time roled up in a rucksack. I've probably worn them about 6 - 7 times, twice for a full days' use. Early use and they were very good. Recently they let me down and I got soaked. I washed and re-proofed them and 2 uses later they gave up after 2 hours in the rain leaving my lower legs very wet.
As for their breathability they were ok, but nothing special. I would be interested in hearing how breathable they are, having got soaked to the skin whilst walking in the rain in my Rab eVent jacket. As far as I can tell it was down to sweat unless there was leakage through the seams, as the water was clearly beading up on the fabric.
Its an old idea in overall terms - just like paclite, membrane strata and a huge number of other 2.5 layer waterproof fabrics.
The difference here being that they're using Pertex as a face fabric, which might be fractionally worthwhile in technical terms, although I'm sure the main thing they're after is the instant brand recognition from doing that.
There was some sort of DWR tech they were playing with way back which shared the name but nothing more.
The biggest difference between the minimus and the heavier RAB jacket is actually the face fabric used - its much thinner on the lighter jacket. To be fair, the treatment on them is also different.
All less breathable than Event, although the more breathable ones maybe somewhere near. Dunno how the Mardale stuff compares, probably less breathable.
