Headed to Alaska this summer for the first time. Iliamna Lake for a week to fly fish. Everything I read says to bring the best rain jacket you can afford, all say Gore-Tex by name. This will be my first time to fly fish, so I am hesitant to spend the money for a Simms or similar wading jacket that I may only use occasionally. Waders, boots, etc are being provided. My tentative plan is to buy rain gear that I can use during hunting season and use it on this fishing trip. I'm leaning towards the Kuiu Yukon or Chugach. Any opinions on the Kuiu rain gear compared to Gore-Tex? Anybody that can advise me as to potential pitfalls of using normal rain gear instead of a wading jacket? Thanks in advance.
