I’ve seen some guys carry off man-bags. But not many.
Lots of US men seem to favour the ‘clip it on my belt’ approach. OK with an athletic figure. Less so with a ‘spread’ figure. If you’re Batman give it a go.
If it’s for on the bike, and around about then pop it in a backpack or Camelbak.
If it’s more for mooching then get a coat with pockets. Any old coat. Just put it in the pocket.
The SPI belts made me smile. I can’t imagine finding one of those any more useful than a pocket.
Those Heinnie Haynes Civilian Lab Covert Loader things. Really? Not sure I’d have the confidence to wear one of those outside a CosPlay event. Still, strangely appealing… And some of the other stuff on the site is neat.
Fabric Horse seems interesting. Etsy…again!
Or, just leave it in the drawer and claim you were working on something that needed absolute concentration and that’s why you ignored the ‘phone. Texts get lost in the ether all the time so forget them anyway. iMessages are different.
