how to choose a backpack

The sports backpack uses litres as a unit of capacity. Choose litres under 15l to carry the necessities for your day such as a sweatshirt and a sandwich, and higher litres if you are the sherpa of the group. In case you need additional equipment such as a gearbox, camera or similar, a litre size around 20-30l is perfect. Multi-point lacing systems help keep the backpack steady if you use it on the move.
