Buying tips

Consider the activity you need the pack for: hiking requires more storage and comfort, while running needs a snug fit and minimal weight. Check reservoir size (2-3L is standard) and ease of cleaning. Look for features like bite valve cover, magnetic tube clip, and compatibility with hydration tablets. Brand reputation matters: Osprey and CamelBak offer reliable warranties.
