Versatility of the Hunting Sporran.

[Bugbear]

I don't know; I'm just going by the descriptions. He was wanting a single sporran for daywear and formal.

This is what made me think of those sporrans, from that page I linked to, "These historically inspired sporrans are not only perfect for re-enacting, but also for modern-day Highland attire, both day wear
and formal."

I think Matt Newsome said the "Duin uasal," on that page, is the only sporran you need or something like that. In other words that it would work as a formal or a daywear sporran, but I might be thinking of the wrong sporran.

They do have hunting sporrans in a couple of other sections of the STM site.
