The Deuter Speed Lite is a sporty backpack suitable for mountain hikes or bike rides. The pre-formed shoulder straps and the lap belt ensure that the bag stays in place. The shoulder straps divide the weight of your pack over your shoulders and your back. So you have a lot of freedom of movement. In the handy zipper pocket at the top of the Speed Lite you store your valuables. You put your drinking bottle and energy bar in the elastic pockets on the side of the bag.
