Shoulder bags?

[Coemgen]

Fo carrying around my school stuff, I use a big bag my dad got at some computer trade show. It's big, black, and masculine looking, and has lots of pockets and things inside to hold pencils, calculator, textbooks, etc.

You also could probably get a messenger bag with a suitably masculine logo or phrase from Cafépress.com

If you've never owned one, treat yourself to an OGIO bag. I've had many others but OGIO is top shelf.

If you want what us country traditional Brits. use, "Google" William Powell.I am sorry I am not cleaver enough to get the email address here.Anyway,William Powell are gun makers and sell all the gear--click onto "accessories shop" and up will come pictures of game bags, look at the ones with netting on the front(called the Sandringham? and there is a bigger version too).I have used one for years and they are almost indistructable.Most of the gamekeepers around here(UK too)would have the large version.Hope this helps.
