Lewis Leathers is good stuff.

My brother wears my old Belstaff bike jacket that is 30 yearsold .

Barbour have been making the International jacket [ IN ENGLAND ]for 75 years ,they must be doing something right .

Barbours always look better when they have a few years patina .

I prefer natural material to synthetic and don't mind putting up with a bit of inconvenience [ if reproofing every couple of years can be considered inconvenient]. I have bought 3 textile jackets [First gear ,Santiago and Belstaff Discovery ]in the last few years and been disapointed in all of them ,only one ,the Belstaff , comes close to what I expect from a jacket but even that has too many useless pockets and velcro.A Barbour jacket is cheaper than any of them .
If there is a good ,simple, textile jacket out there [with a waterproof OUTER layer ] ,I'd like to hear about it .

As regards abrasion resistance ,it's obvious that waxed cotton will never be as good as leather .But I do have experience of sliding down the road on my back after coming a cropper at something above 60 mph ,I was wearing a Belstaff and jeans ,the jean's back pocket wore through and the Belstaff had scratch marks ,I guess I was lucky .Personally ,these days, I'm more concerned about the initial contact with terra firma and I'd like to see Barbour make an armoured bike jacket like Belstaff ,I'd buy one for sure .

Maybe my son has the right idea , he wears a tight fitting armoured leather jacket and ,when it rains , wears my Barbour over the top of it .[ no wonder I can never find it !]

Whatever you choose ride safe.
