Seaweed Tencel Open-Side Top – Black

A loose, sleeveless top with open sides and gathered shoulders, in a soothing SeaCell™ × TENCEL™ blend with Icelandic seaweed minerals active at the skin surface. Wide-cut deep armholes drop past the bust for an open, breezy fit, while soft fabric gathers cascade across each shoulder into a sculpted, draped silhouette.

Mineral-rich fabric that soothes as you move. Relaxed drape, zero restriction.

Why This Blend Works

28% of this fabric is SeaCell™: a fiber made by embedding nutrient-rich Icelandic seaweed into the lyocell production process. The seaweed retains its natural minerals, including calcium, magnesium, and vitamin E, which are activated by your skin's natural moisture during wear. Your skin is most absorbent when it's warm and open. An open-side tank in summer heat is exactly that.

The other 65% is Lenzing-certified TENCEL™ lyocell, made from sustainably harvested wood pulp in a closed-loop process. It adds silky smoothness, fast moisture transport, and enough structure to hold the drape without collapsing.

We add 7% ROICA V550 biodegradable elastane: a certified biodegradable elastane that gives the fabric shape recovery through hundreds of wears and breaks down at end of life. The remaining 93% is plant-based fiber.

No polyester. No nylon. No synthetic performance coatings. No chemical finishes. Just fibers that work because of what they are.
