Perhaps I'm the last person in the world to know about this, but if you have a good cycle jacket, or a bag or rucksack perhaps, that has been damaged or is wearing out, it's possible to have it mended.
Scottish Mountain Gear is based in Unit 19 of Fisherrow Industrial Estate, and is the 'official' partner of Gore Bike Wear. For example, their machinists can replace zips and pockets and velcro, and repair seams and tears, and at pretty reasonable prices.
I visited them the other day, and they now have my well-used Goretex jacket for some repairs and recumbent-orientated modifications. I'll report back here once it's ready.
