I use Technowool by Woolrich. Best thing out there---IMO. Naturally water repellant, and the increased strength of the "enriched" fibers in the product allows not only for better air circulation but also for a much lighter garment.

The added benefit is almost no color fading. Think back 50 years to the days of tarton wool coats worn by everyone who hunted. Find your Dad's or Grandpa's and guess what---the coat looks like it was just pulled off the shelf---no color fade.

Wool is a BIG plus in my book---but I also hunt in the Northeast, where the weather requires a versatile cold weather fabric.
