Liners is key for max sales in my opinion like Wooly and Peroria stated. If you can buy one jacket for most seasons, thats huge right there.
I personally have 3 diff jackets for different seasons. But the heaviest/warmest is too bulky for Bow Season.
I only bow hunt, so adding extra pockets for ammo isnt a must, but might be a nice touch for a gun season.
I do like Peorias idea of sound proofing it, but the trick is "quieter" material is going to collect unwanted shrubbings/stickers/stuff that just sticks to the material.
This year I bought this for the female I took out in the great outdoors
Under Armour Women's ColdGear Infrared Ridge Reaper Jacket - Dick's Sporting Goods
It appealed bc it was warm and cute for her lol. Pending the female hunter, that might be all your girl needs to develop bc of her marketing audience.. A eye appealing, lightweight, warm jacket.
