How about some truth on the hunting shirts? Some of these slogans may hit a little close to home so procede with caution and remember that the truth sometimes hurts. How about:

"Your decal on your truck doesn't make you a hunter."

"You're not on a hunting team, you're advertising for free."

"Most hunting 'associations' and 'foundations' are for profit, but you get a cool bumper sticker".

"A lot of money is made by making you think you're on the 'Team'".

"Most of the gear you think you need is just a gimick".

"Your favorite hunting show is really an infomercial".

"I've known a lot of people that hunt but very few hunters."

Sorry if some of these sting a bit but I've been guiding hunts and doing hunting videos a long time and I'm sad to say that it's true. Team "your product here" is just a way to sell merchandise. Most hunting groups such as the Texas Trophy Hunters Assoc., are for profit and are a business and the small inner circle of owners couldn't care less about you.
Quit worrying about casual gear for hunters, use the same casual wear you use at the house and you'll be fine. A logo on a shirt or your bumper doesn't make you a hunter.
