Fabric: 145 g/m² 100% Cotton (certified Organic or Organic in Conversion).

G/m² stands for grams per square meter and is a unit used to describe the weight or thickness of the fabric a t-shirt is made of. The higher the number, the heavier and thicker the fabric will be.

When it says 100% Cotton (certified Organic or Organic in Conversion) , it means that the fabric is made of cotton, but there is a difference in how the cotton is grown and processed:

100% Cotton means that the entire fabric is made from cotton fibers. There is no mixture with other materials such as polyester or viscose – it is pure cotton.
Certified Organic Cotton : This means that the cotton is grown without the use of synthetic pesticides, insecticides or artificial fertilizers. Organic farming focuses on sustainable farming methods and takes into account both the environment and health. The cotton is certified, which means that it meets the requirements and standards set by a recognized certification scheme such as GOTS (Global Organic Textile Standard).
Organic in Conversion : This refers to cotton grown on a farm that is in the process of converting from conventional to organic farming. This means that the farmer is working towards organic farming methods, but the field is not yet fully certified organic. Once the conversion is complete, the cotton will be eligible for certification as organic.

In summary, this means that the t-shirt is made from cotton that is either grown organically (without chemicals) or is on its way to becoming organic, making it a more environmentally friendly choice compared to conventionally grown cotton.
