I am 5'11 and weight 260 pounds 18 stone 8 I think. Most of my American blue jeans are either 40-36 or so.
Normally I wear a XL camo pant.
A friend in Germany has a hunting shop, and offered me some close out priced Blaser hunting clothing, but the pants are confusing the heck out of me.
I have bought pants from Blaser that were size 60 and they weren't even close to fitting.
I was told by someone similarly sized that size 30 is what I needed.
