Do you guys live in the north? To be honest, I've never paid much attention to the numerical weight of jeans I've bought. More just a "these are thicker than these" observation. I know out here, I can find myself at a bar after 10PM and it is still 95+ outside. Summerweight doesn't sound so bad for that, but am curious to judge relative to others' experiences.
If it's 95 out, I'm in shorts
My go to pair right now is ~19oz and I have a ~14oz pair that I wear nearly yr round.
