We work with several mills. The mills making our organic cotton fabrics are all GOTS certified. We have worked with them for many years. These companies are our main weavers and knitters.
We work with Egedeniz in Turkey, they make most of our jerseys. This is what they say.
The origin of cotton is Aegean region of Turkey (Near İzmir). We always obtain our own cotton from contracted farmers. Our spinning house is in Denizli. Depending on the quality or lead times we may use diffirent knitting and dying houses placed in Denizli,İzmir or İstanbul. All facilities have to certificated otherwise it is not possible to give GOTS certificate to the final items (fabric or clothes)
All of the facilities (Farms,Spinning,Knitting or even warehouse where the finished fabrics are controlled and packed) have to carry the responsibilities that certification requires. The certification is made by non-profit certification companies like ICEA or Control union.

There's lots to know about bamboo, it grows freely without chemicals but the process of converting it to yarn uses chemicals. The same chemicals are used to make paper and soap. Our bamboo silk and bamboo drape is 100% bamboo viscose. The process for these fabrics is done in a closed loop system. This is the company that makes most of our bamboo viscose fabric. http://www.liahren.com/
Our bamboo yarns are certified by OEKO-TEX 100 as being free from harmful chemicals. This is a good article about bamboo, viscose, Tencel etc https://oecotextiles.wordpress.com/category/fibers/viscose/
Dyed bamboo is dyed in an OEKO-TEX certified dying unit.
I would urge you to research yourself and make your own decision. We take the view that it is far less harmful to people than conventional cotton growing.
Our jerseys are made in Turkey. We do have an organic cotton and bamboo mix jersey. The mill buys the yarn from this company - bamboo - The yarn is Oeko-tex certified.
The dyes are Oeko-Tex certified. Superjersey is made from 46% bamboo viscose and 46% organiccotton and 8% Lycra.
