I'm just curious where/how you'd wear jeans that heavy?
Aren't they hot as hell to wear? Or is the weave 'loose' enough that they're comfy up to the low 70's?
If you have ever worn heavy denim over at least 17 ounces and actually broke them in they are amazing and make light weight denim feel like trash. People over on the IH forum even wear them in summer, some dudes even have 21oz cut offs there that dedicated to heavy denim. In reality as long as your skin is not sensitive you'll be pleased with the quality and appreciate the weight.
I had a pair of Iron Hearts that I wore for about a year. Broke them in pretty good and they had a nice soft hand to them at the end, but they were still noticeably thick in a suffocating way. Definitely one of the most solidly built pieces of clothing I've had though, I'd want to wear them if I drove a motorcycle or something
