Can't give any brand names really but I have always been fond of carhartt type canvas bib overalls. Make sure if you go that route to get the reinforced front of the legs type. That way when ripping through brush, briars, and the like it doesn't get torn up. I also wear them around for a little while and wash them to "break in" the legs cause carhartt are mostly stiff when new. I like the overall cause you don't get stuff down your pants and keeps your shirt from getting untucked and they don't fall down when walking in them.
For a vest get one that fits good with what you'll likely be wearing up top. I HATE a baggy vest that catches on things or that feels like it's going to swallow me whole. Also you don't want one fitted to tshirt weather when you may have a thicker jacket. Room for extra shells, water, and the essentials. I HIGHLY RECOMMEND taking multiple chapstick for not only your lips but your cheek bones if it's crazy windy and cold. Nothing will ruin a hunt like painfully cracked/chapped lips or wind burn face. Some sort of lotion for the face would be ideal. Maybe a backup lightweight "cheap" vest if it gets hot weathered on you. I always wear merino wool leggings so if it's hot I just leave them in the truck but if it's cold I add them under my overalls.
