The Daylite Expandable 26+6 can carry a compact travel load and then become a destination daypack. Its main compartment expands from 26 to 32 liters, while a suitcase-style opening makes clothing easier to reach than it would be through a narrow top opening. Leave the expansion unused initially if you want space for the return journey.
A small travel bag with two packing states
Osprey gives the unexpanded size as 17×13×6 inches and the empty weight as 1.85 pounds. Expanding adds two inches of depth. That change is useful for an extra layer or a purchase, but it also changes the exterior you must compare with a baggage allowance. Use the dimensions for the state in which you will actually board.
Open the clothing compartment without digging
The main zipper opens in a suitcase-style format, with a mesh divider and an internal tie-down strap. Those features suit a small clothing load you want to see at once. A laptop sleeve sits against the back wall, while two stretch side pockets keep bottles outside the main packing space. The front pocket gives a separate place for an item you want to reach quickly.
Change roles after arrival
The AirScape back panel combines mesh with ridged foam, and an adjustable sternum strap helps position the shoulder straps. A luggage pass-through is useful when this backpack accompanies a roller. For a day out, leave the clothing at your accommodation and close the expansion; carry only the objects needed until you return. This format is less compelling if every day's load already requires all 32 liters.
