Sustainability that doesn't get your underwear in a twist

Kind to you, kind to the planet

We take our responsibility to look after the planet very seriously and we care deeply about what kind of world we're going to leave behind for future generations. For too long, the fashion industry has ignored its effects on the planet. Did you know that only 3% of underwear is sustainably sourced? We were shocked by this statistic too which is why we're so passionate about making a difference. 

All of our products are made from TENCEL™ Modal, an amazing eco-friendly fabric that represents a milestone in the development of environmentally sustainable textiles. Made with wood pulp from sustainable tree farms, TENCEL™ are the most sustainable fibres around. A naturally sustainable and soft fibre that starts with the tree and ends with the softest fabric you’ve ever felt. Every 5 minutes 10,000 fashion items end up in landfill. Our briefs are 95% biodegradable so when you are finished you can put them in the compost!

Our Production Process

TENCEL™ is the trade name for the Modal fibre that all of our products are made from. Manufactured by Lenzing in Austria, meaning 'ten' for the tenacity of the fabric and 'cel' as it’s made from cellulose or wood fibre. TENCEL™ Modal fibres are extracted from naturally grown Beechwood, by an environmentally responsible integrated pulp-to-fibre process which is self-sufficient in energy and recovers co-products from component parts of the wood. 100% of the raw Beechwood material is converted into cellulose and other bio-based, bio-refinery products, and the surplus energy is recycled into the production of other fibres at the same production site.

The European Beech forests grow naturally without the use of chemical fertilizers or artificial irrigation. Lenzing only use wood from unprotected forests and every tree is regenerated, so anything pulled down is offset with replanting. The production of TENCEL™ Modal uses 95% less water to produce when compared to cotton and reuses 100% of the water from the production process. This flexible fibre is renowned for its exceptional softness, and the resultant fabrics display excellent colour retention, breathability, and moisture management. All TENCEL™ standard Modal fibres are biodegradable and compostable under industrial, home soil and marine conditions, thus they can fully revert to nature. So once you are finished with your briefs you can cut off the lace and put them in the compost! From their botanic origin to the low environmental impact of production, to eventual biodegradability on disposal, TENCEL™ fibres exemplify sustainability in the textile industry.

B-Edit: 100% Biodegradable

B-Edit is our world-first collection of 100% biodegradable lace underwear, sleepwear and loungewear. Using the absolute latest in sustainable fibre technology, we've combined 71% Tencel fibres (wood), 19% Seacell (seaweed) and 10% Roica elastane to create a world-first, fully compostable collection. Don't believe us? Watch our briefs biodegrade in 180 days here.

SeaCell is made from sustainably produced algae, the seafaring plant that is fast growing and gentle on your skin. Roica V55 is our replacement for traditional elastane that takes 20-50 years to biodegrade. This world-first stretch fibre technology from Japan biodegrades in just 6 months and has the same stretch and recovery properties as elastane. Roica smartly breaks down at the end of its life without releasing harmful substances into the environment. Designed in London. Grown in a forest. Composted in your garden.

Tree Planting

We’re extremely proud to be partnered with Ecologi, an amazing initiative helping to take on the climate crisis in the form of planting trees and reducing our carbon footprint. For every order placed, we plant a mangrove tree in Madagascar, so far planting over 80,000 trees! Together we're planting a forest, reducing carbon, restoring wildlife habitats, and creating employment for local families.

Madagascar is more than just an island from an animated movie. It’s a nation with over 200,000 species of plants and animals that don’t exist anywhere else in the world. But more than 90% of Madagascar’s original forests have been destroyed, displacing entire animal species, and taking away the Malagasy’s ability to farm and live on the land. Entire mangrove estuaries are gone, leaving the bare earth to wash away into the sea. Our donations support the non-profit Eden Reforestation Projects as they continue to reforest the island. Eden are world leaders in responsible reforestation, having already planted 26 million trees and created 2.6 million workdays for local communities.

Our Factories

Sustainability, authenticity and empowerment is at the heart of everything we do. These key principles mean the factories we work with are highly scrutinised, only accepted as suitable partners if their policies are in alignment. We have a few factories we work with for the different steps of the production process. Our main factory is with our partner Adam and his small team of 50 in Guandong, China. We also work with Fonte Faria in Portugal who manufacture our B-Edit collection, plus two local embroiderers based in Devon. All of these factories are free of child and forced labour and provide employees with a safe environment to work. Every worker in our supply chain is paid the living wage or above.

Our main supplier Partner is Adam who has worked tirelessly to help us create the perfect knicker since 2017 and even sourced the sustainable TENCEL MicroModal fabric we all now know and love! Our Creative Director Katie has worked with Adam for over 12 years and he is the kindest, fairest man we've ever met. Although China has a bad reputation for the quality of the products and their working practices, Adam’s factory is a notable exception. His factory pays over the average rates for the best staff, offering career opportunities to many people from small villages who'd otherwise not have the opportunity to work outside the village where they were born. Allowing them to save money for a few years before they return to their villages, although many don’t, meeting their life partners and staying in the cities they work. You don’t just have to take our word for it! Listen to this Ted Talk by journalist Clara Vuletich who took a deep dive into the fashion industry.

The B-Edit is milled at Tintex, a Lenzing partner in Portugal, a world leading jersey manufacturer bringing textile innovation to the next level. The range is manufactured at Fonte & Faria, part of the Business Compliance Initiative. The factory was founded in 1994 by two partners Jose Faria and Manuel Fonte and since 2004 has one owner Jose Faria. The factory is large, modern and can produce around 4000 units per day. Employees have lots of technical knowledge and receive continuous training enabling high quality standards.
