Durability and Comfort without Microplastics

Mother Nature and human ingenuity converge in the banana plant. Grown to feed billions and resilient enough to withstand storms, its pseudostems—once discarded as waste—hold fibers long used only for craft.

St3ms™ transforms these fibers into performance-first yarns and textiles for today’s global industry—where durability matters, impact is modern, and consumers demand materials that endure without compromise.

St3ms™ serves the markets where endurance is everything—until it isn’t, and the material can return safely to the soil.

Welcome to St3ms™: the materials brand powering the 21st century with performance natural yarns and textiles.

Delivering Brands with Modern Performance Materials

St3ms™ was founded on a simple discovery: the stem fibers of banana plants can be transformed into performance materials. We advanced them through yarn spinning. Our team comes from global brands and manufacturers, where we saw first-hand the urgent need for natural materials that deliver on performance, impact, and economics.

Modern brands require more than innovation — they need resilient supply chains that scale immediately, materials that outperform without disrupting existing line plans, and ingredients built for a 21st-century future. St3ms™ delivers all three.

Abundance

By harnessing one of the world’s most abundant and regenerative agriculture byproducts, we extend the usefulness of the crops that already feed billions.

Spun to Perform

Fibers from the pseudostems of banana plants form the backbone of St3ms™ technology: yarns — microprocessors of soft goods and brand DNA.

St3ms™ Difference

Performance-First

Higher tensile and tear strength demonstrated in early trials. The team at St3ms™ is straight from performance brands and global spinning plants; and we understand the demands. Performance with impact is our differentiator.

Natural Alternative, No Plastic

100% natural, microplastic-free replacement for cotton-poly blends. Most ingredient brands use plastic to improve the strength of product; St3ms™ found something better and it’s 100% from plants, after food production, and is waste.

Compatibility

St3ms™ yarns run seamlessly on traditional short-staple spinning lines, and our textiles follow proven cotton preparation, dyeing, and finishing systems. This is how scale happens—immediately.

Traceability

Feedstock originates from the global food system — we work with suppliers verified by Rainforest Alliance / GlobalG.A.P. and we’re pioneering traceability through DNA with strong technology partnerships.

Get on the list.

St3ms™ is preparing for launch with mills and customers already in queue. We fulfill yarn and textile orders while supporting the brand releases that will introduce St3ms™ into market.

You’re not just sourcing a material — you’re joining a partnership. One that gives you access to continued innovation, redefining performance materials built to endure.

Enduring brands — reach out.

This is a yarn built for the future: durable, compatible, health-positive, and ready for the world’s most enduring brands.
