The Boblbee GTX 20LBackpack doubles as the highest rated spine protector approved by TÜV. It also protects your gear, laptop, camera and other equipment. The improved GTX series features the Point 65 AirVent, which is part of the back plate design. The special ventilation channels running through the ergonomical back plate keep perspiration to a minimum. Its aerodynamic dome reduces fluttering at high speeds and is water repellent.
