re: Life Jackets and waterfowl hunting

I’m impressed by the responses of people wearing PFDs, obviously you all don’t hunt in my area. So for those that don’t wear them, why not? Comfort, bulkiness, looks, etc.... I have an inflatable one, but I find that the damn thing is so incomfortable on my neck when wearing a heavier jacket. I haven’t tried a float coat, not sure how warm they are and or bulky.
