I have a set of these and am very happy with them for "round town" riding (for any real distance I feel a bit "naked" in them and prefer my Cordura pants with hip and knee armour). The kevlar covers the thighs and knees as well as the butt. They are great for hot days but they are a bit heavier (and therefore hotter) than standard jeans.
Apparently you can get velcro on pads for the knees and hips. I do not have these so cannot attest to their comfort or otherwise.
The jeans themselves are a good fit, well made and comfortable to wear on the bike. They are cut extra long so if you have short legs like me you will need to get them shortened.
At $240 odd dollars they are not cheap but a whole lot cheaper and less painful than the plastic surgery that you will probably need if you have an off in standard jeans. I know there will be someone out there who will tell you he had a 150kmh off in his jeans and he survived just fine - ignore him. He is either a liar (the actual impact speed after braking was probably considerably less) or he landed on the grass. After more than 20 years in the rehabilitaion business I can assure you regular jeans will last about a metre on tarmac before you start to lose skin. And no it doesn't have to be a fast off - 40kmh+ will do just fine. Don't wear them on your bike!
Spend the money and get some Draggin Jeans!
