This is funny. I have a jacket that's almost identical. I purchased from Target three years ago. It was under the Mossimo WorkWear label. The one I purchased is a slightly faded navy blue. I remember them having the faded olive green, I should have gotten one.
Unfortunately these are no longer available since it was from three seasons ago. I imagine the one worn on screen is more likely from a different maker. It will also be difficult to find right now since we are into the Spring/Summer clothing season.
Although "Jack Bauer" from the boards works on props for 24, he may not discuss anything related to the show as I believe while under contract he can't. However itÂ’s worth asking him.
I'll post a pic on my jacket later today.
Speaking about hoodies, have a look at this one:
Green hoodie from Target I know it's not the same color, however the cut seems similar.
FYI, I just checked Ebay and there are a couple jackets like mine. While not the correct color, they could be dyed. Search using the following term: Mossimo Men jacket
