I checked out some of the brands you mentioned, and holy crap they're expensive. Outlier has 3 t-shirts on offer for $300, shirts from most of those brands average $150, Acronym are selling jackets for $1k+....
I'm expecting a reply on the line of "quality comes at a cost" but I've got shirts over a decade old that have no visible signs of wear and cost a tenth of what these cost.
