Thanks to the perforated, ergonomic shoulder straps and the minimal back support of the Airstripes back system, the Stepout excels in maximum air circulation and high wearing comfort. The roll-top volume expansion, the side pocket for a mobile phone, and the elastic side pocket ensure quick access to essential items. Inside, the document and laptop compartments, along with a water bottle holder, provide excellent organization. The fabric of this PFC-free product, certified with the Green Button and bluesign standard, is made from 26 recycled 0.5-liter PET bottles.
