To carry over from another thread, I got a Montane Lite-Speed windshirt on Ebay and it arrived today.
It is what I expected: fairy-light cloth, spare on details that would add weight, a Spartan way to keep the wind from sucking the heat away from my body and still vent the buckets of perspiration that come from my lumbering mass when I try to make it go up steep hills.
This one hits the scale at 5.8oz in the XXL size. I'm glad I ordered the XXL and I normally have no problem with US sized XL clothing. It's roomy enough for a microfleece shirt and/or a vest. I expect it to work very well with a light polyester base layer.
The little stuff sack that comes with it is cute, but asking for trouble trying to stuff the jacket in there and worse yet trying to pull it back out. It will be great for tossing a bear bag line over a tree branch.
Montane should have put a double zipper on the chest pocket so it self-stows. I'll use it that way anyway. This thing will fit in a vest hand-warmer pocket or a cargo pocket in pants or shorts. Cool :)
I like the ventilation panels running up the inside of the sleeves, under the armpits and on down the sides. This won't be such a greenhouse. I have a Sierra Designs windbreaker that is a well made garment, but it gets a little steamy with no vents.
And now I'd like to go off a little about windshirts....
Didn't we used ta call 'em windbreakers? What's the big deal? They are a light windproof outer shell to keep the wind from convecting the heat away from your body. They've been building them in one form or another since the 1960's that I know of. The fabrics have certainly gotten lighter, but the general build and function is sure close to the same.
Rant II: I can see a lot of function in a good ol' nylon shirt-- you know one with a couple pockets and buttons down the front and sleeves you can roller blind up and down, and a collar you can flip up to keep the sun from turning your neck into a southern United States stereotype. And you can wear stuff underneath an oversized shirt just like a "windshirt." Some of this fanciness is a lotta hooh-ha. I'm glad I only paid $35 for this rather than something closer to the $95 MSRP on this one.
