I had a go with one of these at the weekend and I was amazed at how much loft they've got out of the down. Very impressive. With it being Arc'teryx it is obviously really well made.
However... the jacket just didn't fit me. I own four Arc'teryx jackets so am used to their relatively slim fit but this was seriously tight. I found under the shoulders too tight (and I've hardly got a bodybuilder's back) and the sleeves too short (and I've a negative ape index!). The jacket's body is very short but that's what it is designed for. I actually checked to make sure I hadn't picked up the wrong size and my mate even wondered if I'd picked up the women's model! Arc'teryx claim the fit is designed around the Atom LT (which I own) but I think if that's the case then they've forgotten that down lofts to twice the thickness... Definitely a brilliant jacket, but try before you buy or even go up a size.
Excellent test. I am surprised Petzl don't do this sort of testing themselves and stick the results online! It would be great to get like-for-like testing like this across their range.
I can't believe the differences between some of the units, it's amazing. I've only ever used fairly budget torches but my mates' Myos et al have always really impressed me. This shows how much light they blast out very clearly. For camping, most night running, and winter/alpine walk ins the cheap torches offer plenty of power, but I'd hate to have to, say, winter climb with a low-output torch (or by torchlight at all!)...
Black Diamond for me. They're the only manufacturer to make gloves with fingers that aren't really long. Punishers are perhaps the standard Scottish winter glove. Skytec Argons and 'Chamonix Binman' gloves are good cheap options, though. Rab and Mountain Equipment make excellent gloves for climbing but they don't fit me. Avoid ski gloves because they're not designed for the dexterity of climbing. Try them on in a shop and try doing clove hitches, tying laces, etc. with them on.
I'd have 3 pairs of gloves with me on any winter climbing day: leather gardening gloves for the walk in and gearing up, my BD pair for climbing in, and a pair of mitts to wear on the walk out, if I drop a glove, or if shit hits the fan.
There's some excellent points raised above, and two very good links.
Mole, I think you're about right. Gore got it bang-on 30 years ago with Gore Tex generation 1, which would have breathed like a monster. I've even heard arguments that it would be more breathable than Pertex because it has more holes in it. I don't believe a word of that, but it was clearly seriously impressive. The problem was of course it leaked once oiled up so Gore rushed to stick the PU backer on it, which is a technological cul-de-sac and makes it air-impermeable. The guys at Arc'teryx (well, BlueStone) told me that Active Shell was as far as Gore could go with their PU technology - they'd made it as thin as they could. The big secret on new Gore Tex Pro was out at Outside in 2012 - that it has no PU - but they haven't, of course, given away how they are keeping the membrane from getting contaminated. If it's two layers of PTFE, as shown above, then I think it will still be ruined by oils after a while, unless they're coating the pores a la eVent. I think Goretex Pro is almost certainly more breathable than ProShell, but at the expense of durability. eVent and Neoshell are just the same: very breathable, but less durable. Neoshell is great because they've brought the 'academic favourite' of electrospinning and been brave enough to make it commercial. I don't know much about making membranes, but electrospinning is the future of many technologies, and I wouldn't be surprised if Gore and whoever now owns eVent aren't pouring money into electrospinning at a serious rate of knots. Electrospinning PTFE is a total nightmare but they might have other clever ideas. Gore's PTFE membrane with an electrospun PU backer would be very breathable and exceptionally durable (and probably expensive...).
I wrote some bumff on breathable fabrics a couple of years ago on the 'other channel'... http://www.ukclimbing.com/articles/page.php?id=4556 Some of it is starting to look dated but 95% of it is still relevant.
There was little or no thought behind what I just gabbled... but to answer the question, I'd say Pro is more breathable than Proshell but less durable, and nothing is ever as good as the hype.
