I hunted moose in Newfoundland last year. I think it rained every day, with 3.5" falling one day. The issue was more of keeping dry than keeping warm.
Those Lacrosse boots pictured above look good. I wore Muck boots. I took one of my homemade wood boot jacks to make getting the boots off easier. We walked 1-4 miles every day out in the bogs. Its a lot like walking in the tundra in Alaska.
Rain gear should be "waterproof", not just "water resistant." A wide brim waterproof hat would be beneficial. I also took a collapsible camo umbrella that was nice when we were sitting and glassing bogs.
The rifle that I took was my stainless steel, plastic stocked Rem 7 mm Rem mag. I taped the muzzle every day, and dried and oiled the rifle and bore every night. One of the other hunters in camp shot a cow moose one day, and while I was talking to him the next day I could see rust in the bore of the muzzle of his rifle.
I don't think Newfies know what sun screen is.
