Ooh, I rather like the design. I think the cord jacket just brings out the inner geography teacher in me.
I thought that, but they've missed a trick. Retroreflective elbow patches!
There was a thread over on CC, started by a lady who'd converted a jacket she found in a charity shop - a light tweed one, I think. She'd sewn retroreflective tape on the collar, the cuffs and the buttoned placket across the small of the back. Inconspiciously grey in the light, obvious in the dark with a light shining on it.
A good source of the tape, if you can be bothered with a little work, is the hi-vis waistcoats sometimes sold in poundshops. The waistcoat is nasty thin mesh usually, but the tape is pukka scotchlite, and over a metre of it per vest. Unpick it, sew it or stick it to anything you like.
