A 65L backpack describes storage volume, not a universal carrying weight or body size. Start with the equipment, food, and clothing your trip requires, then compare how the actual pack fits your torso and hips.
Capacity can be more than necessary for a light outing or insufficient for bulky shared equipment. For flights, compare the packed dimensions and weight with your airline’s current allowance. A 65-liter label alone does not establish cabin eligibility, comfort, waterproofing, or an included water reservoir.
