If you’re in search of a quality baggage option that allows for hands-free travel, Osprey’s Porter 46 and Aer’s Fit Pack 3 are two pack leaders worth considering.

Weighing in at 1.5 pounds with a whopping 46 liters of capacity, it’s made to accommodate a substantial amount of luggage.

In contrast, the Aer Fit Pack 3 is a more compact travel companion with strategic allowances for efficient packing. Its dimensions play out as 20 inches in height, 32 inches wide, and 44 inches in depth – translating into a total of 18.7 liters of storage space. Despite offering lesser volume than the Porter 46, it wins on compatibility, being suitable for use with a remarkable 83% of airlines.
