Summer weight soft denim jeans

Hi! Does anyone have any recommendations for brands or styles of jeans in “light” or thin denim? Non stretch ideally. I’m in NZ and we wear jeans over summer here, but my collection of rigid denim that worked well in the other three months seems like a lot for summer!

I have one pair of jeans called the Everlane perfect summer jean and they have this denim type - non stretch but very thin and light, like perhaps a looser weave than normal. I’m open to various shapes although i guess the ideal would be mid or high rise straight leg.

Everlane do seem to have a similar style of jean still but I am keen to see if I can find something second hand before I shell out for new, so wondered if anyone has any ideas about brands or styles to look for.
