Brazil's tropical climate and many beaches mean there is a high turnover of beachwear, with many people constantly buying new pieces to keep up with the latest beachwear trends. Most beachwear is made from virgin nylon or polyester, and much is discarded after minimal use, ending up in landfills or incinerated. 

Levh develops fabrics in partnership with the Italian company Econyl® to create regenerated nylon made from fishing nets and other types of nylons discarded in oceans and landfills for its swimwear collections. Econyl® is produced through a closed-loop regeneration system, which starts with the recovery of polluting waste from the oceans and landfills worldwide. These materials are firstly sorted and undergo a cleaning process to recover as much nylon as possible. The nylon waste is then recycled back to its original purity, processed into yarns, ready for the fashion industry.  

Levh also works with technical and biodegradable materials, developing fabrics which decompose in a maximum of 3 years. This is a much faster decomposition process than the more commonly used petroleum-based fabrics, which take about 150 years to degrade under the same conditions.

The cotton used in Levh's collections is 100% Brazilian (national) and certified by BCI (Better Cotton Initiative). This global non-profit organization guarantees sustainable cotton production, with transparency and traceability of processes.

1% of the value of each piece sold is donated to the institutions SOS Amazônia (NGO whose mission is to promote the conservation of the region's biodiversity) and EcoSurf (an organization that protects and conserves beaches and oceans). In addition to the ecological material, they also partnered up with RioBike Courier to deliver orders by bicycle in Rio de Janeiro, Niterói and São Paulo, helping to avoid more than 4 tons of CO2 emissions per month. Levh's packaging consists of reusable, plastic-free eco-bags or cardboard boxes for e-commerce.
