That is putting sewing to good use.
I used to gold at a course that didn't allow drinking. One time when we got out of sight of the clubhouse, and the marshall, my buddy pulls out something that looked like an umbrella bag and began producing cold beer. Turns out Moosehead had put this "cooler" out that you stacked eight beer on top of each other and zipped up. I thought I could use one as a barrel bag for the C9!! Pick one up if you see it, comes in handy for those golf excursions that you aren't allowed to drink on, although courses that booze isn't allowed on oughtta be outlawed!
Cheers
