## Customer feedback

Customer feedback highlights perceived durability, storage capacity and appearance, with reports that the bag can hold a 13-inch laptop and a large A4 ring binder. Those impressions are relevant to its listed laptop compartment and 27 L capacity, but the laptop anecdote does not confirm the fit of every 15-inch device. Feedback on size is mixed, including comments that the shoulder straps feel too small, so fit may matter more than the headline capacity for some buyers.
- Positive themes: Customer feedback describes the backpack as durable and appreciates its storage and design.
- Mixed feedback: Feedback on size is mixed, including reports that the shoulder straps feel too small.
