Polartec has just come out with a new waterproof breathable fabric that is supposed to breath like event, and feel like a softshell. It is called neoshell. Sounds like a great hunting shell fabric. We will have to see what happens.
Here is the info. Some big names are making garments with this stuff. But, oh so pricey.
The KUIU fabric is good stuff. Check out their website and blog. They did a lot of homework trying what Sitka did to the next level. Plus your putting your dollars toward a hunting company who supports the industry and conservation, unlike the anti hunting stances of the other guys.... Just a thought.. : )
