The Mariner's Study Shell Tee | Unisex
A study of the sea, recast for autumn. The Mariner’s Study Shell Tee brings together antique shell specimens in a warm, weathered palette inspired by changing leaves, salt-worn coastlines, and the collected curiosities of an old mariner’s study.
Available in Earthy Olive Heather, Silver, and Heather Clay, each colorway pulls something different from the archival artwork; from deep mossy greens and aged ivory to rust, teal, ochre, and sun-faded red.
Soft, lightweight, and comfortably lived-in from the first wear, it’s an easy layer for crisp coastal mornings, wandering old harbor towns, or whatever autumn adventure finds you.
