Sitka Timberline jacket?

I did check that, based on ME wearing the stuff. I think it breathes better than any rain shell I've ever owned, and I've owned them from a bunch of different companies. Maybe it's a sweat box for YOU, but not for me. As for the no taped seams, Sitkas new Mountain Jacket, Timberline Jacket, and Timberline pants, all use taped seams in their construction.

And I'm telling you it a WB membrane that's been flattened and stretched in fact it is same as cabelas 4most wind shear. Any one that has used the woolimate or Berber series can tell you it's not breathable. So to say it's more breathable then any waterproof breathable on the market including gore is incorrect since its is a gore waterproof membrane..... Why tape the seams? Unless it's waterproof? Draft in the seams that's marketing at its greatest.

Texan, I thought when they stretched it, it opened up the pores more and made it more breathable? Is that not correct? I could have sworn the pores on the windstopper laminant were large.

You are thinking of the pores as a true holes, think of it more like Swiss cheese now flatten it. Flatten and stretch is really for less laminate being used, ultimately justifying lower price point. Also laminate doesn't have a protection layer so many holes will clog quickly. On top of that is gore's original membrane which wasn't breathable to begin with. Why I asked for real scientific specs on wind stopper breathability. 99% of with wind stopper/blocker/wind shear etc is same flattered and stretched membranes.

I like the use of wind blocking type technology(laminate) for still hunting and glassing but not moving a bunch. Hard to beat cabelas woolimate for stand hunts but don't wear it on a long harsh walk. Regardless I'd treat it like rain gear and not get a jacket with out out zips if you where going to use it during high activity.

It's kind of like kuiu saying their new jacket is wind blocking by construction... No knit is going to block wind. Might reduce it but it won't touch a laminate for wind blocking, but will be more breathable since there isn't a laminate membrane.

http://www.verber.com/mark/outdoors/gear/breathability.pdf here's a good read, broken down scientifically. Windstopper, by all accounts, is the first gen Gore Tex, without the PU membrane added to it. It will show up as the expanded PTFE in the charts.

First you are taking a guess that the expanded PTFE is windstopper... It is not. But ill humor you.

Look at the liaminates mentioned look at the cititation dates. Only one is still relevant after 10 years.
First note that the PU film is mainly to protect the membrane, original gore-Tex didn't have a PU backing( i.e. Windstopper)

By looking at the pdf about the only relevant premium WB still being used is Event. With a breathability rating of 25k(at most humidity levels). It's running pretty damn close to an expanded PTFE. Now toss in Toray Dermizax NX, event DVstorm, 37.5/concona, Schoeller(new stuff), outdry extreme..etc some of those membranes have a higher breathability then windstopper at certain humidity

Any way wind stopper is a laminate, breathable is relative term, being a laminate it's going to wear like a laminate. You're a big Sitka fan I get it. Sitka has always produced a good product, with that said windstopper being breathable in high exertion activities is an oxymoron. Gloves sure vest sure.... a soft shell is breathable windstopper is not even close.

I'm only going off of what Google searching for a few minutes came up with, I own far more First Lite than Sitka, and I can only go off of my experiences with windstopper and how it worked for me. I don't own any Sitka windstopper gear at the moment, not sure if I'll purchase any or not, certainly have other things higher on the priority list.

Would be interesting to see an updated chart like the one linked above, but that might blow some of KUIU's claims out of the water. Everything they produce is a miracle fabric :)
 
You mean Torays claims. :)

Kuiu Puts together a good product. love them or hate them they have been good for us the consumer. (I wouldn't run thier pack, just not sold on CF including bows). Sitka puts together a good product, think Sitka could be even better with out gore textiles. I'll give kuiu and Sitka credit they got awesome media departments.

I don't think anyone would ever be able to say anything bad about firstlite. Very well ran company. Their partnership with Concona was huge for emerging technical fabric companies.
 
So I'll answer my own question here. I bought a Timberline Jacket and holy crap...it's my new favorite jacket. It's awesome. I love my Jetstream, but it's too heavy to hike and ascend in. But the Timberline is perfect, breathes and eliminates the wind chill. For me, I can handle sub-zero temps; but throw me some wind in 50* when I'm sweaty and I get chilled. This thing went with me on my goat hunt for two weeks and I wore it every day up the hill. 40's/50's and wind with spitting rain over a baselayer and it was perfect. I had it in some decent rain, just shy of a downpour or soaking rain and it did well. For me, it was the weight and the wind. I think they just made the 90% obsolete and may've really put a hurtin' on the Jetstream.

Awesome jacket. I kept thinking, "Sitka really hit a home run with this thing." Maybe pit zips? Even without pit zips, I didn't soak myself ascending every morning.
 
I've been playing around with a Timberline since spring. It's an amazing jacket. I keep holding off on a review because I keep double checking my findings (they just seem to good to be true). It's a great jacket for windy ridges and mountain terrain. I want one in a a solid color now!
 
Been pretty thrilled in mine. Was over 12K for a week. To block wind it worked perfectly. And at a lb if I don't want to wear it, it packs down very small.

Not sure I'll mess with any of my other soft-shells again. I think the weight and packability and fit make me a fan of this one. It seemed to breath well to me as well.

What's the difference between this and the older jetstream lite? Only thing I see is tapped seams?

Seems like a heavier duty fabric to me, but not heavy. I have a JS Lite vest for comparison...and maybe the fleece in the shoulders.
