This thread needs more photos! Here is the indigo Selvedge stripe chambray. Lightweight at 4oz (https://www.weargustin.com/store/2517)
I have this shirt and it was one of the best G buys. Price was right, fabric is great.
I have a pair of 9oz'ers and I don't really consider them jeans. They look like jeans on the outside but they wear like a different item entirely. Flimsy would be a good word to describe them but not in the sense that they will break or tear at any moment. It's just with that light a fabric, there is no heft or substance to the pant when comparing to a standard 14oz pair of cone denim or something like that. My 9oz pair definitely has a purpose though and I'm glad I have them. Any daytime event in the sun that doesn't involve gym shorts, they are my go to pair. I personally don't like shorts at all so having a pair of denim that I can wear to a festival, concert, outdoor party, etc. is a nice option. They're out of place when its below 70 though.
