  • sustainability

    At Crossfly, we're dedicated to sustainability in every aspect of our business. From our products to our packaging, we prioritise eco-friendly methods and materials.

    • Our IKON products are crafted using sustainably sourced modal fabric
    • 100% recyclable packaging; entirely free from plastic

    Read more about Sustainable Modal

    Modal fabric, renowned for its luxurious softness and durability, is a prime example of sustainable textile innovation and this is why we have chosen modal over cotton or bamboo. Derived from beech trees, a replenishable and fast-growing natural resource, modal production boasts significantly lower environmental impact compared to conventional cotton cultivation. Unlike cotton, which requires extensive irrigation and pesticides, modal production relies on a closed-loop process that recycles water and chemicals, minimising waste and pollution.

    This eco-conscious approach not only conserves water but also reduces energy consumption, making modal a standout choice for environmentally conscious consumers.

    Moreover, the unique properties of modal fabric extend beyond its environmental benefits. Its exceptional breathability and moisture-wicking capabilities make it an ideal choice for clothing such as underwear. Despite its luxurious feel, modal fabric is impressively strong ensuring longevity. And, this is why we tell our customers to "Buy Nice and not Twice".

    By opting for modal-based products, consumers not only contribute to environmental preservation but also enjoy high-quality, sustainable goods that stand the test of time.
