Aberdeen will never be known for being a hotbed of liberal male couture.
The guys around here carry bags in all shapes and sizes.
Admittedly, the colours usually are the blue, black, brown variety but that just equates with male fashion generally.
My own one is an ex R.A.F. side pack with the regulation shoulder strap in air force blue.
Great little general purpose holdall.

Finally, I go for option Z which is just what I damn well pleaZe!
