Billi London Launch The New SEV7N Biodegradable Leggings

Billi London recently launched their new SEV7N Biodegradable Leggings.







The Billi London SEV7N Biodegradable Leggings were available exclusively in their pop-up stores in London and Paris, but can now be purchased online.

Billi London have already created the world’s first certified 100% biodegradable tights, and have now decided to do the same with leggings. They are made with a blend of innovative enhanced biodegradable yarns, using 3D technology for maximum durability and superior comfort.



With a unique mix of innovative enhanced yarns, Billi London leggings break down in a record time of around 5 years (versus 40 to 100 years for traditional leggings made with standard or even recycled materials) into biomass and biogas, creating renewable energies, and without leaving microplastics in landfills.

Billi London leggings are ethically and sustainably made in Italy with solar-powered production and water recycling facilities.



To get the fit and feel of the SEV7N Biodegradable Leggings right, Bill London co-created the design with the help of customers who they consulted on every aspect of their ideal legging design, from leg length to how thick the fabric should be.

Key features:

• Black
• Premium and luxury yarn: Amni Soul Eco® nylon and ROICA ™ V550 elastane
• Appearance 150 denier
• Curves toning and sculpting effect to beautify your natural silhouette
• A soft seamless waistband sewn by hands with natural tummy flattening effect
• 3D technology allowing a 360-degree flexibility
• Comfortable and soft for a second skin effects

The Billi London SEV7N Biodegradable Leggings are available in four sizes: S, M, L, XL.

The Billi London SEV7N Biodegradable Leggings are priced at £54.00 or €61.00.
