Looking for a wind proof layer for under a wool jacket. Any input would help greatly.

I use a golf windbreaker (both top and bottom) if I want it under. When I want it over I use my suede type rain gear.

It seems strange no one seems to make a simple under layer wind break.

Cabela's windsheer fleece vest

I have a Sitka Gear vest that's very light and pretty good at blocking the wind.

Asbell makes a wind blocker vest.
right now I only see a zippered version.

I have a pullover type widblocker vest (no zipper)
It works GREAT!
adds some warmth too.

Maybe you can get one w/o the zipper if price is a concern.

Patagonia or Kuiu goose down jacket...very lightweight, compressible, quiet, windproof, and warm.
I'll only wear this on the coldest of days, or long sits.

in the clothing forum there is a asbell full sleeve wind breaker top...if you wear a medium if not....

I use a Cabelas pullover sweater w/wind blocker built in.Some folks think it's noisey in sub-zero temps,I've had no problems spooking animals.I like it a lot.

I have always had best luck, wearing my wool, as an underlayer! A good wool sweater or jacket, covered by a soft tight weave cotton or 50/50 cotton poly Camo shirt or jacket, really beats the wind & rain!!! Plus, it keeps the wool closer to your skin, where it does the most good...!! OMMV

Duluth Trading Company Shoremans Fleece is perfect. I wear the vest under my Asbell. Windproof, quiet, extra warmth, fairly economical, and comes in neutral colors.

Try searching climbing/mountaineering gear for 'windshirts'. 'Back in the day' when I climbed I used a single layer nylon windshirt over or under other layers. It was super lightweight and it packed small enough I could carry it in a pocket.
Hope this is helpful.

I also use a he pull over sweater from cabelas. It has the wind shear in it and it works like a charm. It is not noisy at all. And on days around 40 degrees I wear it as my outer layer. 100% wool shell keeps me warm.

Gore Windstopper

golf wind shirt

Predator Camo Adrenalin jacket works great for that

I have two of the Asbell wind blocker fleece Pullover High Collar Vests and they work awesome.... Collar is Higher in back than front but if you extend it up you're covered nicely, otherwise roll it down and you have extra neck thickness....

Used golf wind shirt from a Goodwill or other thrift store usually runs about $3.99. There isn't a better layering option for as little money.
