Its overall size is also expressed as both 20.3D x 34W x 48H centimetres and 18.9x13.4x8. Confirm the selected listing’s laptop compatibility and measurements before buying. Water resistance is claimed, not waterproofing. The advertised TSA approval and security-opening claims are not independently confirmed here.
