I would like to buy breathable water-resistant hunting gear (not cotton) in multicam pattern. But I don't think it exists. If I'm wrong, will somebody post brand names or a link?
I picked up a set of wild things rain gear for cheap on ebay brand new. The massif combat shirt is pretty nice as well as the massif soft shell vest. Check out pants made out of defense m fabric. Its a rayon nylon kevlar blend. 782 gear is also pretty nice looking. Theres also some multicam patagonia stuff. If you can get to a thrift store near an army base you'll find some stuff. Also the usgi level 6 stuff is goretex packlite and level 5 is 3 layer soft shell. Its really not bad stuff at all.
The wild things pants come up from time to time at some good prices. Check out fortbragg.us for some good usgi gear and those defense m pants. Cities on craigslist that have army bases nearby is another suggestion. There's a wild things kit that's available fom time to time on ebay and comes with most of their items in multicam. I saw one go for 750 ish but its around 1800 worth of gear.
Have you taken a look at Crye Precision? They are combat gear type of clothing but it is closely related to what Sitka and Kuiu are doing, along with their prices.
