O bag has always invested in research, and the careful selection of raw materials is entrusted to laboratories whose production is strictly made in Italy.






Innovative and ultralight, XL Extralight® plastic is one of the “brand ingredients” that has determined the success and iconic identity of the brand.

The most of the bodies 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 part of O bag bodies, O shoes slip-ons and O slippers.






The imperfect Flip flops are made using compounds specially designed to support higher percentages of recycled vulcanised material, which is ground, processed and purposely treated so as to be returned to the production cycle. This procedure, stemming from ongoing investment in research and development, guarantees the use of 55-63% of recycled E.V.A. compared to the virgin polymer mass. The entire production process has been verified, standardised and certified under UNI EN ISO 14021:2016. Each production lot is recorded and tracked. The flip flops form part of the O zone collection, the green O bag project reflecting its commitment to an increasingly circular economy.



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
