Cabin Max

Cabin Max builds its Metz and related underseat bags to dimensions that closely match several well-known budget-carrier personal-item limits — a genuinely more checkable claim than a vague “fits under most seats” description, though it’s always worth confirming the current allowance for the specific airline being flown.

Its structured bag shapes hold their size consistently, which makes them easier for gate staff to judge by eye than an unstructured, soft-sided alternative.
