Deuter Flyt 14 - The weight-optimised, TÃœV-certified Flyt protector backpack has been reduced to the essential features. A light, removable back protector provides protection in the event of a fall. There are clips on the outside of the backpack or side compression straps to fix the helmet. Two stowable straps at the bottom of the backpack also allow bike protectors to be attached. The proven, light Airstripes system also ensures sufficient, pleasant ventilation on the back.
