How fast is 30L Backpack growing?

A 30L backpack is a versatile medium-sized backpack with an internal volume of 30 liters, making it suitable for a range of activities from daily commuting and gym use to weekend trips and day hikes. This size is particularly popular for its balance of portability and practicality, allowing enough space for essentials like a 16-inch laptop, a few days' worth of clothing, toiletries, and other necessities, while often being compact enough to qualify as a personal item on most airlines. Many 30L backpacks feature multiple compartments for organization, padded laptop sleeves, and designs that prioritize comfort with features like padded shoulder straps and breathable back panels.
