Harbor weather doesn't hold.
You leave the dock at 7 AM in a hoodie and by 10 you're carrying it. By 2 PM the wind shifts and you wish you had it back. That in-between window — too warm for a full layer, too cold for a short sleeve — is where most people get caught underdressed.
The Seaport Long-Sleeve Heavyweight Tee was built for that window.
240 GSM Cotton. Not a Suggestion.
Most long-sleeve tees are an afterthought — thin fabric, loose construction, something to throw on before a real layer. This isn't that. At 240 GSM, 100% cotton, it has enough weight to hold warmth on its own and enough structure to sit flat under a hoodie without bunching at the shoulders or riding up at the waist.
It's the piece you reach for when the weather is making up its mind.
Built to Layer. Built to Stand Alone.
Under the Navy Blue Pullover Hoodie or the Heather Gray Pullover Hoodie, it adds a clean base layer without bulk. On its own, it's enough for a cool morning on the water or a long afternoon on the dock when the sun is doing most of the work.
Two ways to wear it. One piece that earns its place either way.
The Details
- 240 GSM 100% cotton — heavyweight enough to insulate, breathable enough to move in
- Embroidered Seaport logo — clean, not loud; the kind of branding that holds up after a season of real use
- Seaport Authentic Gear patch — a mark of what this is built for
- Available in Navy Blue and White — both work on the water, both work off it
Harbor Weather Changes. Your Base Layer Shouldn't.
The long-sleeve tee is the most underrated piece in a harbor kit. It's not the statement. It's the foundation. Get it right and everything else layers better, fits better, and holds up longer.
