There is no one jacket to cover your hunting needs in diverse conditions. I had a wonderful brown plaid Woolrich heavy wool jacket i used for many years until it got accidently washed in hot water and shrank.
I could wear it in light cold rain, layer under in bad cold, stalk through wet brush, killed stuff from winter quail in south texas to moose in BC.
This would be good but the dry plus wont last 20 years.
