Two liters is a small difference; a different backpack layout can be a much larger one. The tomtoc 38L Travel Backpack has its own rectangular design, visible straps, and front access arrangement, distinguishing it from the existing 40L model. Compare the way each one would hold your belongings before treating 38 versus 40 as the deciding number.
Plan the load that will travel together
A 38-liter bag belongs in a main-luggage comparison for many packing styles. Lay out clothing, toiletries, and equipment together, then identify which rigid objects determine the interior arrangement.
A pair of shoes can force a different packing shape from a soft layer. Likewise, a computer kit can consume space that appears available for clothing when you look only at an empty backpack.
Look at access while the bag is in use
The product image shows a different front layout from the rounded 40L option. Review the interior and opening photographs to decide how you would reach essentials when the bag is upright, and how you would repack it at your accommodation.
Keep your comparison focused on actions you repeat. Retrieving a charger without moving clothes, separating a used layer, and closing the bag quickly can matter more than a feature list detached from your routine.
Screening wording does not determine baggage fit
The listing describes the bag as TSA friendly. That wording is not an approval of the backpack and does not guarantee that electronics can stay inside at every checkpoint. Follow the instructions for the screening lane you use.
For cabin planning, obtain the exact exterior dimensions and compare the packed profile with your ticket's allowance. Capacity alone cannot establish the correct baggage category.
Choose this 38L model when its verified arrangement works better for your clothing-and-equipment load than the neighboring tomtoc options, with the size and access decisions resolved together.
