I just received my heavyweight American jeans today via Priority Mail. They are 14.75 oz. They have a nice textured, beefy feel but not super heavy. I will wear them in the summer heat, no problem. They remind me of some of the better LVC denim from 2003-2004. I look forward to trying them on, but my arm is in a sling after surgery and pulling on brand new denim may take a few more days of rehab.
