The world's first backpack made from recycled sea plastic rethinks sustainability. In our oceans, coral reefs produce most of the oxygen we breathe. A major factor in coral death is plastic waste. With your purchase, 3.5 kg of plastic will be recovered from the sea. Wherever your paths take you - the recycled plastic never gets back into our oceans. As a strong companion, it is particularly light, robust on your back and the material is 100% water-repellent. The waterproof fabric and the sealed proximity keep your valuables dry. With the flexible roll top and compression straps, the 23 liter volume can be easily expanded. A removable laptop bag secures your equipment. We've got your bag!
