Received my second pair of pants from Luxire today. Fit is nicer, a little low for dress pants but find for chinos. My request for fine cotton lining did not get glossed over. The lining on this pair, while unsure if it is shirting fabric as requested, is certainly of a nicer feel and quality than my previous pair.
The navy twill chino, and I assume by extension the other similar fabrics, are nice and thick. I'll make sure to update after some hard wear to see how the fabric holds up.
