Good stuff here and thanks for the replies. JasonM, your use is exactly why I brought this up, and that is the way I would use it, to block wind and spray. I am not worried about getting overheated and sweating because I would not be involved in an activity where that would happen. I am not walking in to spots or wading 100 years across mud and wouldn't be. I was thinking of it for transiting in the boat, and on rainy days when it is around 40 degrees or less.
That being said, I like what you had to say about the gear you are using DHinton. Neither the Dakota hoodie or the duck oven are listed as rain gear, and that is a must to keep water off. What did catch my eye is the delta pro wading jacket. I do not like long coats, they are a PIA hunting out of a sneak, and I prefer a jacket to a parka style garment. That might fill the bill and give me the performance and uses I want this for, and will probably go with that. Sitka is good stuff, and I get it if it costs too much for many, I just look at it different. What is the value of the product short and long term? I don't like buying things twice. It is why I have high end simms waders for fly fishing, a filson winter coat, and allen edmonds loafers, and why I live in the town I do. The current pair of simms is new but the last ones lasted me damn near 20 years with a minor repairs around the neoprene booty seam tape. I don't need a lot of stuff, I just need good stuff. And my old jacket? Have gotten 20 years out of that, but it is gore-tex also, and the water resistance on that material does wear out and you can't really fix it. In todays dollars I paid as much for that as the delta pro costs now, and I got my money's worth and think this jacket would give me the same or better.
I also use neoprene waders for colder weather hunting, and again, I am launching the boat, getting into it, going where I want to hunt, pulling it in the grass, and that is pretty much it. The amount of strenuous activity is very minimal unless I get caught on mud when the tide goes out, which I am pretty good at avoiding these days. Sweating is not an issue in that usage, and they keep me warm and dry.
