Umm, hunting jackets are pretty technical. Mine is one of those 4 in one dealios.
The shell is a microfleece surface with goretex, waterproof and breathable. It can be worn as an uninsulated jacket.
The liner is basically thinsulate sandwiched between two pieces of fleece, and only goes down to the waste.
Normally, when hunting you would zip the liner to the shell to make an insulated parka. But when fishing, I wear them as separate pieces, the liner inside the waders, and the shell outside. The shell is a little long for a wading jacket, it's parka length. But you can wade over it with no problems.
