This is a pretty interesting article to read if you're in the market for riding jeans. It's mostly targeted for riders who want an understated jean you can wear all day, on-and-off the bike.
Of the jeans listed, I own a pair of UglyBros Triton jeans, which will be replaced by rotating between Iron Heart jeans and Rev'it Carnaby jeans, the latter being shipped from Revzilla at the moment.
I loved my Uglybros jeans; fit was perfect, style was perfect, even the knee pad placement is ingenious (pocket inserts are on the outside instead of the jean's inner lining; near-guaranteed fit and easy installation/removal). But the integrity of the 12oz denim wasn't enough to hold up against everyday wear after 12 months, so I've lost confidence of its ability to protect from abrasion.
I chose Iron Heart to test the integrity of a heavy 21oz denim jean, and chose the Rev'it jeans for its Cordura weave, I'll definitely post updated reviews in the near future.
Notes: The Rideapart article's a little dated: if you were interested in Uglybros & don't mind having crotch holes from sitting on a bike every day, there's a US website & vendor in CA:

Iron Heart has an american Vendor in San Francisco:

I also advise against clicking the Dethkillers link on the Rideapart article; I tried clicking it on a work computer during my lunch break once and it wouldn't grant me access, saying something about malicious malware/spyware, something like that.
