Me and a few mates have them, have done since 2007, they were replacements for the RM/ SF smock with no wired hood, or rank tab. They're really good bits of kit, slightly heavy for a CJ and really hot in sunny weather, as the mesh lining does the good stuff of cooling but being windproof there is no where for the heat to go. My zips are pretty much always undone.
It fades really fast too and then holds its colour thereafter (if that makes sense?) But it is washed in Nikwax Tech Wash.
I also fould it slightly baggier than normal CJ's too.
sf clothing is rather gucci i must say, got loads of built in features for e & e like wire sewn into the seems for snares, razors in the collars, button compass on the cuff, loads of other hidden extras aswell. it also has the mesh pockets and compass pouch etc sewn on the front and under the arms.
