acetate - Nice to know and need to know

The green fiber

Acetate is categorized as an environment friendly fiber because it is manufactured from wood pulp. Wood pulp is a renewable resource from the nature, grown in closely controlled wood pulp forests. Reforestation programs ensure adequate supply of acetate fibers for the industry. Acetate has also shown to be biodegradable and can be composted or incinerated with no harm to the environment.

The Comfort Factor

Fabric extracted from acetate provides a high level of comfort to the wearers. In particularly, it is beneficial to use acetate fabric for the lining as acetate has better moisture absorption properties, as compared to other synthetic fibers. This characteristic ensures better sweat control for wearers, enhancing their comfort levels. Also acetate fabrics drape well and conform to body contours without clinging. A scientific ‘Comfort Study’ conducted by the Institute of Environment Research at Kansas State University indicates that acetate linings are less damp, less sticky and more absorbent compared to polyester linings.



When technology helps us see the world through different eyes.


Our lenses are engineered by the German manufacturer of optical systems ZEISS. The company was founded in 1846 and they operate within all kinds of optical lenses, including sunglasses, and is well known for superior quality.

For our eyeglasses we use the ZEISS CR39 lenses providing 100% UVA/UVB protection



To ensure functionality, high-precision and a prolonged life of our eyewear, we use German nickel-free 5 to 7 barrel hinges from OBE and safety screws with silicone coating.

OBE has established itself as a key supplier for the optical industry since its founding in 1904. In particular due to their leading role, when developing spectacle hinges.
