For me I find the Anorak design the best in ridding. The front is completely wind proof and they pack small. I am selective in getting the 100% Nylon type as they are not water proof and breath well. The only thing missing is armpit vents. On one of my Anoraks I just sewed in some zippers. Nothing fancy.

Get your Anorak large so it can go over your clothing.
Bright colors are fine but get dirty easily and are hard to clean.
You want it made of thin material so it packs easy.
Dont get water proof. If you need rain protection get a rain jacket.
Dont get Polyester as it will feel like you are wearing a plastic bag.
Dont spend allot of money on it. Remember that you dont take anything in the field you cant afford to loose.



100% Nylon Packable Wind Breaker Anorak - 20 USD when you find them and can be hard to find.

RATS - Just went on line and cant find the 100% Nylon ones for less then 40 USD. Really there is not that much to them. Its just a wind Breaker.
