The Always-In-Rotation Tank
The Merino Silk Rib Tank is the one you’ll reach for again and again (and again). Made from a breathable, odor-resistant blend of organic merino wool and silk, this ribbed essential keeps you cool when it’s hot, warm when it’s chilly, and fresh all day long.
Long in the body with plenty of stretch, it layers like a dream, moves with you, and always bounces back. The silk adds a subtle sheen and strength, while the chlorine-free Plasma treatment ensures it’s machine washable. No outfit planning needed—it just always works.

CARE
To keep your item looking its best, gently machine or hand wash in cool water. Avoid soaking or bleaching.

Merino wool is nature’s performance fabric—moisture-wicking, odor-resistant, and breathable, all without a single chemical treatment. Blended with silk for added softness and strength, this ribbed essential keeps you feeling fresh, comfortable, and effortlessly put together.
And because great clothes should go the distance, the Merino Silk Rib Tank is part of our (re)Nui pre-loved program—so you can trade it in, pass it on, and help keep timeless staples in circulation. Less waste. More wear. A better way to dress sustainably.
Good for You, Gentle on the Earth
Here’s the truth: Most clothes are made from cheap synthetic fabrics that leak microplastics, trap sweat, and wear out fast. The MerinoSilk Tank? It’s natural, breathable, and built to last.
