## Osprey Daylite Plus 20L

Our rating: 7.7 out of 10.

Best for: Weekend travelers and commuters who want one light daypack that also works as an under-seat personal item.

The Osprey Daylite Plus is a daypack first and a travel bag second, and that is its strength. At 20 liters and about 1.3 lb empty, it is the lightest bag on this list by a wide margin, and it works for a commute, a hike and a flight without looking out of place on any of them.

For travel, it fills the personal-item slot. The listing measures it at 18.9 x 11 x 9.4 inches, and the soft body squashes down further when it is not stuffed full. A padded sleeve takes a laptop up to 14 inches plus a tablet, and Osprey's mesh-covered AirScape back panel keeps it from sticking to your shirt on hot days. Two side mesh pockets take water bottles, and a front stretch pocket holds a jacket.

The limits are capacity and layout. Twenty liters covers a weekend with careful packing, not a week. Its main zip does not open the bag flat like a suitcase, so anything packed at the bottom means digging. The 14-inch sleeve rules out larger laptops. Budget airlines with strict personal-item boxes may still reject it when full.

## tomtoc Navigator-T66 Travel Backpack 40L

Our rating: 8.3 out of 10.

Best for: Carry-on-only travelers packing for 3 to 5 days who want a backpack that packs like a suitcase.

The tomtoc Navigator-T66 is the bag on this list built for one job, which is carrying everything for a short trip in the overhead bin. At 40 liters and 20.47 x 12.99 x 9 inches, it fills the common US carry-on size of 22 x 14 x 9 without going over, so you get the most packing space a legal carry-on allows.

The main compartment unzips all the way around like a suitcase, so packing cubes lie flat and you can see everything at once. A separate laptop section takes machines up to 17 inches and opens 90 to 180 degrees, so it can lie flat in a security tray. A front quick-access pocket reaches into the main compartment in flight. tomtoc uses YKK zippers and recycled polyester, and the bag weighs about 1.2 kg empty.

The trade-offs come with the size. Fully packed, 40 liters is heavy on the shoulders, and the padded straps and chest buckle help less than a real hip belt would. It is too big to use as a day bag at your destination. Some European budget carriers set smaller cabin limits than US airlines.
