One item no one has brought up... clothing.

Example: If KUIU or Sitka offered a 'Mountain Hunters Package' where I could pick and choose a base layer, insulating layer, outer layer, rain coat, and some accessories.... send them all in my size, let me try on, wear for duration of hunt and send back for them to clean up for the next guy, I would absolutely rent the clothing package. Clothes don't have to be "broken in" like boots. And I buy enough used gear that I wouldn't care if someone else wore it.

It doesn't make a lick of business acumen for any major clothing company to do such a thing. Make people buy what they want to try. But if someone had the money to buy each years new line, in all the sizes, and rent it out - I'd probably take a look if the price is right.
