Long time ago. Over 3 summers, I worked out of a 21' Chestnut freighter canoe on the Churchill River, doing fisheries research. 60" wide, V-stern & a long-shaft 18Hp motor. Probably 10 months, adding up the days. We wore whatever the weather delivered. Usually rolled up our rain gear and stuffed that into rubber boots. Black flies (Simulidae), No-see-ums and mosquitoes were a nuisance but the horse flies even chased the bears and moose out of the forest and into the river.
I suggest that you pick out the worst & worn clothing that you have with every intention of leaving it behind.
When you get to civilization, find the local native fine art sales outlet for shopping.
