The Soltis waterproof solution:

It is manufactured with Serge Ferrari® patented Précontraint® technology, ensuring that it does not deform, does not form pockets, and has a very long useful life. The colors are maintained despite the passage of time. It is a light and safe textile that adapts easily to various designs. It is fire retardant: In the event of an accident, it consumes itself without leaking like other vinyl-type materials. It is 100% recyclable: The Texyloop program allows you to completely recycle textiles and prevent them from contaminating when incinerated or disposed of in landfills.
