I gotta go with Pokey on this one. I've seriously thought about Kevlar jeans over a dozen times like when those "Sliders" go on sale at Comp Acc, but I think you're better off getting truly armored overpants for not a whole lot more dough. First, Kevlar jeans aren't Kevlar everywhere, just on likely abrasion locations, so if you slide on un-armored parts, you're back to denim protection. They can also be stripped or rotated on your body. And there's no impact protection - the Kevlar only protects from sliding abrasion (and maybe pellet rounds - lol). They can fit weird and I've heard they're a bit toasty in the summer after you've gotten off to eat or hike or shop or walk around, so their utility as an all-day pant is reduced. They don't offer any cool-weather or rain protection. Based on Pokey's and others' suggestions, I picked up a Firstgear HT overpant and am really happy with them so far. Super easy to get on and off with boots, are armored and abrasion-resistant, are waterproof, are ventable and cost less than you'd think from Mike of RidersDiscount. They fold up nice into a top box too, so you can take them off and walk around in your normal work or casual clothes between rides.
