For full-day backcountry tours, 25–35L is the ideal range. Choose 25L if you pack light and tour in mild climates, 30L for most full-day tours (this is the most versatile size), and 35L if you carry camera gear, tour in very cold climates requiring more layers, or tend to bring extras. Going below 25L means you may not have room for essential safety gear, food, and layers. Going above 35L adds unnecessary weight and bulk for day tours.
