Hiking is a physically demanding activity. Your backpack should support you, not hinder you or affect your posture. Always try the pack on to see if the waist belt fits your body type. 80% of the weight of the backpack should be on your hips for maximum support and comfort. When it comes to materials, you can never go wrong with waterproof and splash-proof to ensure your belongings are safe. Choose the right capacity for the time you need to travel as well as the right material for your backpack depending on the environment along your destination.
