Versatile storage options include two mesh side pockets, while front and top zipped pockets and a key clip keep valuables safe.

A mid-volume day pack with internal organisation and a laptop sleeve, the Flex 25 backpack keeps you prepared for every eventuality.

Find Your Back Length

Place your hands on your hips and tilt your head forwards. Ask a friend to help you measure from your C7 vertebrae (the bony protrusion at the back of your neck) to your iliac crest (the top of your hips). This measurement will give you an idea of which back length to choose for the best fit.
