To preserve domestic tranquility, it is mandatory that I cease tracking chips into the house and that my shirt pockets and pants pockets stay clean of chips. Even my cell phone which stays in a pants pocket is filthy with chips. Apron or Smock? Brand?

I've done the google search and there are, of course, many options. My requirements are:
covers front pockets
keeps chips off the neck area and from coming down the neck of the shirt
long enough to keep pant's pockets clean
Preferably fairly light. I'm in the south and it's hot!
All thoughts valued. Apron vs Smock?
Thanks
