What to Compare Before Buying
- Cabin size: Check the 45 × 34 × 20 cm unexpanded size and the 45 × 34 × 25 cm expanded size against the dimensions you need for your chosen airline or underseat space.
- Capacity: The bag changes from 30 L to 38 L, so compare the smaller and expanded formats with what you plan to carry.
- Laptop size: The compartment is stated to fit laptops up to 17", so confirm your device size before choosing.
- Storage layout: Review the compartment and pocket layout if you want separated storage for clothing, accessories and valuables.
Choosing the Correct Version
The main choice here is whether you want the bag in its compact 30 L format or expanded 38 L format. The same backpack gives both options through the unzip expansion design, so check the packed size you plan to use most often before buying.
Before You Decide
Confirm the expanded and unexpanded dimensions, the 17" laptop compartment and the pocket layout before choosing this backpack. If you want an underseat cabin bag with extra room when needed, the expandable format is the key feature to check.
