Zero Waste by Urb'n Nature has upgraded its sustainable spa and hotel amenity collection with 100 per cent plastic-free, compostable disposable spa underwear made from plant fibres, cotton and modal.

Formulated from cellulose, modal is entirely plant-based meaning the underwear is suitable for vegans. Plus, modal is considered a sustainable fabric option, as less water and energy are required during its manufacturing process.

“Plastic-free sustainable spa underwear is just one of our brand’s many ways to tackle the overuse of single-use plastic in spas,” explains Jörg Demuth, product development director and co-owner of Zerowaste by Urb’n Nature.

Designed to cater to allergy sufferers, the underwear has been designed to be soft, crease-resistant, robust, breathable and have a cooling effect on the skin.

The disposable underwear collection is designed to accommodate all clients and includes spa tank tops, thongs, boxers and briefs designed for both sexes.
