Sustainability.
Fueled for Performance. Driven by Purpose.

Designed for a Lighter Load

Combining high performance with sustainability, we create products that not only leave you feeling light on the court but also leave a lighter load on the planet. Our strings Zero, Sync and Slap are designed to play better for longer with our signature snapback, leading to less string breakage and ultimately less waste. Vivo takes our commitment to sustainability to the next level being made from a recycled polyester source.

Biodegradable Packaging

Moving away from single-use packaging, we opt for the best materials with the lightest load on the planet. Our stencils trade plastic for cardboard. Our sets are packaged with 100% recycled paper — using half the material of conventional string packaging.

Carbon Neutral

Since 2023, reString has been a fully carbon neutral business. Through our partnership with Carbonfund, we offset our entire footprint by investing in certified sustainable forestry projects.

Our partnership with EcoCart takes it further — giving customers the option to offset their own shipping emissions at checkout, turning every order into a climate positive action.

Ethical Operations

We remain mindful of our environmental impact throughout our operations and only choose to work with partners who share our environmental philosophy. As we grow our business, we also look for ways to reduce our footprint - streamlining the flow of our goods and choosing shipping methods which are less taxing on the planet.

Our Mission

Project 01

A Better Packaging for the Planet

We design our packaging the same way we design our strings — by questioning everything. Where the industry defaults to plastic and excess, we see an opportunity to do better. A completely new design — conceived and built from the ground up around three pillars.

  • Sustainability

    Good packaging shouldn't cost the planet. By rethinking what a tennis string can be, we designed packaging that works with the planet rather than against it. Fully biodegradable, FSC-certified, and made from recycled paper — our packaging eliminates plastic completely at a time when most competitors still rely on it, and uses 50% less material than the industry standard.

  • Functionality

    Form follows function. The packaging opens cleanly, stores efficiently, and works without thinking about it. For stringers handling product every day, that ease is non-negotiable. We're a performance brand — that thinking doesn't stop at the string.

  • Beauty

    Design is how we think about everything. The packaging reflects that — minimal, precise, and unlike anything else in the category. The kind of packaging that makes customers pick it up before they even read the string name. Beautiful enough to make them stop. That's what re-imagining looks like in practice.

Project 02

Upcycle and repurpose -keychains made from broken strings

Circularity is the goal. The ability to take a material from start to finish, use it fully, and bring it back around.

We're not there yet — but this project is a step in that direction. Broken strings collected, broken down into small malleable pellets, and remade into keychains. Each one is a unique blend of whatever strings came in — a little more Zero some days, a little more Sync on others. No two are the same color.

A string's second life, worn on your bag.

    Collect and compile our broken strings

  • 02. Clean

    Remove debris from the strings to prepare them for shaping

  • 03. Shape

    Break them down small malleable pellets and mold into keychain shape

  • 04. Full Circle

    Ready to head back onto the court as an accessory.

Project 03

The Stencil — made from recycled material

Our take on the stencil. A two-piece design that brings the finishing touch to your racket.

We reimagined the string. This time, we reimagined what comes alongside it. Moving away from plastic, the stencil was redesigned around the same three principles that shape everything we make.

  • Sustainability

    The stencil was one of those small details we couldn't leave alone. Almost every stencil on the market is made from plastic. Ours is made from recycled cardboard — biodegradable, lighter on the planet, and designed with the same intention that shapes everything we make.

  • Functionality

    A performance brand has to get the basics right. The stencil is thick enough to hold its shape through repeated use, fits cleanly at the top of the stringbed, and stays in place while you work. Simple to use and built to last — even in a biodegradable material.

  • Beauty

    Clean, considered, and unlike anything else in the category. Most brands don't think twice about their stencil. We did. The same attention to detail that goes into our strings and packaging goes into every piece of the reString world — this one included.
