Every product you purchase funds the removal of 15 kg of plastic waste from the environment. This is the equivalent of 1,000 plastic bottles (each 15 gr).

This plastic is collected through Seven Clean Seas and our plastic recovery projects, which are third-party certified and independently verified to ensure every kilogram we recover is traceable, accountable, and removed to the highest environmental standards. But our impact doesn’t stop there. We work in a way that’s socially responsible by directly hiring our cleanup crews from local communities, providing fair wages, proper contracts, social security, and safe working conditions.

So you’re not only helping clean the planet. You’re also supporting an organisation that provides stable, dignified livelihoods for the people protecting it.

We take great pride in our sustainable practices.


Our t-shirts are made on demand by Stanley/Stella, a brand known for its commitment to eco-friendly production and sustainability. Stanley/Stella t-shirts are crafted from high-quality materials and come with several important certifications, including The Global Organic Textile Standard (GOTS), The Global Recycled Standard (GRS), OEKO-TEX®, and PETA-Approved 100% vegan materials, ensuring ethical production and environmentally responsible practices. Stanley/Stella is also a member of the Fair Wear Foundation, which conducts audits to assess human rights risks and monitor Human Rights Due Diligence (HRDD) progress in their factories.

Our recycled plastic products are made from ocean plastic we collect through our daily efforts and are carefully crafted in-house at our projects in Bintan & Batam, Indonesia. Our stainless steel bottles are BPA-free and designed for maximum recycled content and recyclability. These are produced in partnership with our trusted and selected manufacturer in Zhejiang, China. Finally, our tote bags are lovingly handcrafted by skilled artisans in Bali, Indonesia, blending sustainability with craftsmanship

We only print a t-shirt after your order is placed. Not only are you supporting an organisation that’s cleaning up the ocean and helping coastal communities, but you’re also supporting a brand that minimises the need for unnecessary waste.

Note: Your t-shirt will be printed and ready for shipping within 2-3 days.

Yes, we do! We deliver to most countries using tracked shipping. You’ll be able to see the full list upon checkout.

Depending on the shipping method you choose, delivery in the UK takes 1 to 5 days. Shipping to the rest of the world (EU, Asia, North and South America) can vary from 6 to 21 days.

Note: customs and local tax for international orders may be charged separately, and are not included in the final delivery fee.

As part of our commitment to sustainability, we do not process returns or refunds for incorrect size choices, because this means another delivery, new packaging, and more. We ask you to carefully check the sizing details of each product before placing an order.

However, if you receive a product that is damaged or there’s an error on our part, please contact us at hello@sevencleanseas.com with your order number and details. Our team typically replies within 48 hours.

We’re really sorry to hear that! We do not accept returns as we aim to minimise carbon emissions. We encourage you to consider donating the product to a local shelter or secondhand store where it can find a new home. If you have any other concerns, feel free to reach out to us. We're here to help!

In the meantime, we’re working on adding product reviews to our site.
