well- you're a hard fit. Tall, and very thin. whatever size you go with it's either going to be too short some where or too big on the torso. i honestly don't recommend you buying something online if you can avoid it, as you're likely to get stuck with something that doesnt fit well. if you need a size reference, size 52 will likely be your best bet.
Most MX gear (like Thor and Fox) I wear 36" waist. Levi's a 34 and Carhartt's 35" :thumbup:
I'm just looking for a simple pair of black leather (without pucks) pants to wear this summer once I go to my textile jacket so I don't wear out the bottoms to my 2pc leather suit.
I like the looks of the A-star A-10's but they're a bit pricey.
