Nodding to the striped Breton top worn by everyone from French sailors to Andy Warhol, this tee delivers the comfort of cotton with a host of technical bells and whistles you need for your run.

Atwill sourced a unique cotton modal blend that’s silky soft yet seriously sturdy. Made from beech tree pulp, modal keeps this drapey top feeling light and airy.

Narrow blue stripes offer sophisticated French style, which means Mariner pairs perfectly with running shorts or jeans. C'est parfait.
