ive always been a fan of leather, but last week bought myself a HALVARSSONS textile jacket. I bought the short version 'kerax' model i think, ready for a europe/morocco trip soon...its as light as my alpinestar leather, has ziped vents right up the arms, side, chest, back, so plenty to keep you cool, yet it is waterproof gortex & is as warm as my winter jacket when all zipped up...£189 from custom lids in newcastle, but im sure there are other stockists around...best to try on, im usualy a 42 - 44 chest, but a 40 fit me well.

apparently these are now being used by the old bill in UK...
