The sunglasses worn by Taylor Kitsch in the first episode of The Terminal List (2022) and in the first episode of Season 2 of The Terminal List (2026) seem to be Zac Posen Roscoe sunglasses.

The Zac Posen glasses are seen on the boat when Kitsch's character talks to Chris Pratt's character.

The sunglasses have a metal arms with a transparant, plastic / acetate frame on the front side, it looks like the Concrete color.

The glasses are currently not available anymore.

Alternative sunglasses

A similar alternative as suggested by a visitor of the site, is the Persol 5007, available on Persol ($185) or at EZ Contacts ($196) but you'd have to add custom sunglasses to the eyeglass frame.

Taylor Kitsch wears more sunglasses throughout the series, including Randolph sunglasses.

In the same series, Chris Pratt wears Gatorz sunglasses.
