In reply to genericflipper:
I suspect they are Special Make Up (SMU) items, made especially for catalogues and stores. That's why the designs look similar, but usually using different fabrics.
'Online' being mandmdirect, by any chance (that one of the first google hits for the Harrot)?
I notice the Rollo at mandm says 'Gore-tex', but the Harrot as S&R says 'Gore-tex Pro'. And, no, I can't see any difference between the Harrot and Malham jackets at S&R...
Marketeers, eh? Don't you just love 'em...?
