SeaBlend Tank

Meet the SeaBlend Tank by tentree—a sleeveless, sea-inspired tank made from lightweight recycled fibers that help keep plastic out of waterways. It’s a warm-weather go-to that’s made for sunshine.

Key Features: Classic tank silhouette with a crew neckline; wide, comfortable shoulder straps; and a slightly relaxed fit that allows air to flow. The SeaBlend Tank is long enough to tuck or wear loose, depending on your outfit and activity.

Fabric & Feel: The SeaBlend Tank by tentree uses SeaBlend fabric, typically made from recycled cotton and REPREVE® Our Ocean® recycled polyester. The knit is soft, breathable, and just a touch more durable than a pure cotton tank, making it ideal for beach days, hikes, and everything in between.

Why It’s Good: SeaBlend repurposes cotton scraps and ocean-bound plastic into a comfortable everyday fabric. That helps divert waste, conserve resources, and reduce demand for newly produced fibers. tentree adds ten trees planted to every purchase, so your tank contributes directly to reforestation as well as cleaner oceans.

Fit & Care: Regular, easy fit that isn’t too tight through the chest or waist. Choose your usual size; size up if you want a looser, more surf-inspired silhouette. Machine wash cold and tumble dry low or line dry to keep both fabric and fit in top condition.

Style Notes: Wear the tentree SeaBlend Tank with shorts and sandals for beach trips, or pair it with joggers and a light overshirt when you’re heading out on a casual hike or weekend errands.
