There is a small ad in Rider this past issue for a company in Israel that makes biker riding gear. See www.brosh.com . I am a hard fit on riding pants, what with short inseam and knee pads misplaced and so on.I currently wear BMW Kalahari pants with suspenders and Gore-tex liners but they are a bit much in summer and have never been a truly great fit. They make several models of riding pants and they also offer that you send them a pair of your own jeans that actually fit you well(and a little loosely) and they will sew kevlar into them -with pad pockets. The cost is $44+8 sh, plus more if you want the pads from them.
Have you tried this product/service? If so, I would like to hear about how it turned out.
