Recs for Relaxed Heavy Grey Flannel Trousers

I’m looking for a pair of gray flannel pants similar to these. I really like the casual shape on them, especially the one on the right. I’m gonna be wearing them more casually, rather than businessy - pretty much exactly the vibe of the screenshot. Looks like the one on the right is heavier weight, high rise, double pleated, in a relaxed but slightly tapered cut. It’s from an Australian brand, but they’re not selling it in light grey right now. The S&M looks slimmer. JCrew and Todd Snyder are also selling relaxed grey flannel pants, but they seem too wide/straight. Anyone have ideas on something similar, specifically with that relaxed but tapered cut? Or could I get something similar and try to tailor the cut?
