forecheck,
I'm usually pretty adept at telling you whether SP, Nike, CCM, Gemini, or any other company makes a particular jersey, but I didn't see a single thing on the Crusader jerseys that might have identified who made it. If it's not a big-wig like Nike or CCM, I'm sure they'd be ecstatic over doing a bunch of jerseys as long as they had permission from Holy Cross to make 'em authentic. No name-plates, small company, I bet it wouldn't be anywhere near the $180 required for a Sioux authentic Nike.
Side note for those interested: Holy Cross is old-school with not having names on the back of the away jerseys (also significantly cheaper, obviously). Their home whites do indeed sport a name-plate and name on the back.
