How the comparison works

Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.

Source dates appear with each link below. A source date does not confirm today's price or stock.

Pack your bottles before choosing the bag

A tall shampoo bottle and a stack of small jars ask different things of a toiletry bag. Aer’s Simple Kit has 0.5 L of capacity; Eagle Creek’s Pack-It Trifold has 6.1 L. Those endpoints describe volume, not the shape of the opening or the height of an internal pocket. Lay out what you carry, then compare the bag’s dimensions and pocket photos.

Matador’s FlatPak Zipper case weighs 32 g, while the Pack-It Trifold weighs 255 g. The FlatPak is 6.5 in deep; the Trifold is 5 in deep. More capacity does not mean more room in every direction. For a hanging layout, Eagle Creek’s Pack-It Hanging bag offers 3.7 L, so you need not choose the largest bag to get that format.

These are maker dimensions and empty weights, with no packing or leak checks performed. Aer’s Simple Kit has no supported depth measurement here. A waterproof product name does not prove that spilled liquids stay contained, and a toiletry bag does not by itself satisfy airport liquids rules. Use the current rules for your departure airport and secure bottle closures before packing.

Before you buy

Will a bigger capacity hold more of my bottles?

Capacity is each maker's stated volume, not a bottle count, and shapes differ a lot. FlatPak Zipper is 9 by 3 by 6.5 in, while Trifold Toiletry Bag is 10 by 7.5 by 5 in, so lay your containers against those numbers. Matador's 70D ripstop FlatPaks weigh 32 and 34 g for 2 to 2.3 L, while Aer's ballistic nylon kits suit you if fabric matters more than grams.

Are these hanging bags, and will they stop leaks?

Only the Pack-It Hanging Toiletry Bag names hanging, and this comparison doesn't cover hooks, leak resistance or airport liquid-rule compliance for any bag. A Waterproof name, like Matador's FlatPak Waterproof Toiletry Case, isn't a leak test, so bag your liquids separately.

Why does an 8 in size limit still show a 10 in bag?

The size control reads only the first dimension each maker lists. Eagle Creek gives Hanging Toiletry Bag an 8 in first dimension; its second matches Trifold’s longest side and its third matches FlatPak’s middle side above, so it passes a limit set to its first dimension despite its longer second side.
