At O bag, we have always invested in research so that we can offer our customers products that are constantly new.
The innovative, ultra-lightweight plastic material XL Extralight® is one of the “brand ingredients” that have led to O bag’s success and recognition.

The meticulously selected raw materials are sourced from trusted suppliers whose production is entirely Made in Italy: Finproject S.p.A. in Macerata for XL Extralight®, Silter in Venice for silicone and LEM Srl in Varese for the manufacture of sunglasses in Grilamid.




The body of O bag bags is made in XL Extralight®, a special closed-cell expanded foam developed thanks to the research and creativity of Italian company Finproject S.p.A., whose commitment to sustainability is evident in its adherence to the Federchimica “Responsible Care” initiative to encourage the chemical industry to respect and support policies for Safety, Health and Environmental Sustainability, and to the “Cluster Spring” scheme, which aims to create synergy and optimise the development of the entire green chemistry sector.

XL Extralight® is an ultra-lightweight, flexible material that’s colourful, versatile and with an unmistakable feel. Thanks to its closed-cell structure, it prevents the absorption and proliferation of bacteria and is resistant to water, UV rays, chlorine and salt, while retaining its colour unaltered.

When kept away from high temperatures and heat sources, XL Extralight® is long-lasting and also retains its shape.

The material is free from heavy metals, phthalates, chrome, cadmium and other hazardous substances.

     XL Extralight® products are manufactured in facilities powered by renewable energy, thus limiting CO2 emissions for energy production, and in which industrial waste is recovered and reused to create new items, again reducing the use of fossil and other fuels.
XL Extralight® is used for all O bag bodies, O shoes slip-ons and the brand new O slippers.


Non-allergenic food-grade silicon


The straps of O clock watches and the O bracelet are made using non-allergenic food-grade silicon, a synthetic material based on silicon (a natural element found in sand) and oxygen. It’s an extremely high-quality material, suitable for food use and completely non-toxic, odourless and tasteless, non-stick, elastic and resistant to wear and high temperatures.


Grilamid TR90


Grilamid TR90 is a special shape-memory techno-polymer based on polyamide; it is hypoallergenic and biologically compatible, and completely safe when worn in contact with the skin or for long periods. Grilamid is 20% lighter than conventional materials and particularly resistant to shock and stretching, making the product highly durable. Thanks to its flexibility and shape-memory properties, it does not warp even when subjected to high temperatures.

Grilamid is Made in Italy and 100% recyclable.

The frames, arms and lens surrounds of all O sun sunglasses are made from Grilamid TR90.


FSC paper


O bag shoppers are made using paper certified by the FSC (Forest Stewardship Council), which guarantees the use of cellulose from responsibly-managed forests and ensures reforestation.

By using the FSC® mark, O bag continues its commitment to increasingly sustainable solutions.

O bag’s aim is to be an increasingly sustainable brand by always seeking to use greener materials with low environmental impact, and by developing products that combine technical quality and state-of-the-art aesthetics.
