Are the posh jeans significantly more durable? My mighty crotch and thighs (ooo-er!) can trash most pairs of jeans within about 6-9 months of heavy wear, especially if I'm cycling on them, and I'm loath to spend £££ on Japanese denim pairs etc. if they're not going to last any longer.
No and yes. Thicker denim is more durable, so your knees and the outside of your calves won't wear through. But the extra rigidity means any friction areas will probably wear faster than thinner mix material denim.
