Description:

There is a stretch of the year along the harbor — late spring, early fall — when a hoodie is too much and a short sleeve is not quite enough. The mornings are cool, the afternoons open up, and what you want is something that works across the whole day without requiring you to think about it. The Mint Green Heavyweight Long Sleeve is that piece. A single layer that handles the in-between weather the New England coast is known for, without any of the bulk.

Mint is a color that belongs to the warmer end of the coastal palette — soft and easy, the kind of color that looks right near the water in the months when the harbor is at its best. It is not a loud color. It is the kind of color that people notice without being able to say exactly why, which is the best kind. It works on a morning walk along the waterfront, on a weekend on the coast, on an afternoon that starts at the harbor and ends somewhere else entirely.

At 240 GSM, this is a genuinely heavyweight long sleeve — not a thin layer that loses its shape after a few washes, but a substantial piece of cotton that holds its structure and gets better with wear. The embroidered Seaport logo and Authentic Gear sleeve patch are the details that make it specific: understated, precise, and there for the people who look closely.

Why You’ll Keep Reaching For It

100% pre-shrunk cotton means this shirt fits the same way on the hundredth wear as it did on the first. It does not shrink, it does not stretch, it does not lose its shape. At 240 GSM, the fabric has enough weight to feel substantial without being heavy — the kind of piece that drapes well and holds its structure through a full day of wear. It layers easily under a hoodie or jacket when the temperature drops, and works on its own when it does not.

The mint colorway holds well over time. It softens slightly with washing in a way that feels natural rather than faded. After a season of regular wear, it starts to look like something that has been around — which, by then, it will have been.
