The promo backpack is made of 100% organic cotton, with a density of 120 g m2. How is organic cotton different from regular cotton? It is not only that organic cotton is soft, but also that it is cultivated and processed under particularly strict conditions. This type of cotton is grown in an environmentally responsible manner, without the use of fertilizers or pesticides. It only allows the minimum presence of pollutants. These requirements are spelled out in international standards: Eco Content Standard (OCS) and International Green Textile Standard (GOTS). Cotton is 100% environmentally friendly at all stages of the production process, from sowing to harvest and delivery. The GOTS standard also specifies certain social requirements for the organization of production. Enjoy the quality of organic cotton with our TIBAK Promotional Backpack. The backpack can carry up to 9 kg.
