E-04Seatback Access
Moves the bottle off the measurement
An external bottle carrier on its own strap. A bottle in a side pocket adds to the width of the bag; on a sling it adds nothing.
One-time purchase. No subscription, no membership, no recurring charge.
All prices and transactions are in US Dollars (USD).
Free standard US shipping over USD 69. Unused and unopened returns accepted for 30 days — see the refund policy.
Gives up to 4 cm against a fixed opening.
01Measured
Taken off the finished piece, laid flat, with nothing clipped to the outside. Handles and hardware are inside every figure.
Empty, unexpanded
26 × 9 × 9 cm
A loaded figure is only published when we can also publish what was inside it. Where you do not see a loaded row, it is because that record does not exist yet — not because the bag stays the same size when it is full.
02Check it against your own limit
We subtract them from the figures above and show the gap on every edge. No verdict, no promise — the arithmetic and nothing else.
Size Ledger
Take the three numbers your carrier publishes for your ticket and type them in. We hold no carrier data of our own, so nothing here can go out of date.
We compare numbers, not policies. Airlines change limits and measure differently at the gate.

E-04 · Water Bottle Sling
Waiting for three numbers
Nothing is compared until you type a limit. We do not guess, and we do not store a list of anyone else’s rules.
03Specification
Sprayed with 1 L of water at 20 °C from 30 cm for 90 seconds, closed and laid flat. Zipper tape and seams are not sealed and are not part of the test.
This is a resistance rating under the stated test, not a waterproof rating.
Rated to 2 kg. Damage caused by carrying more than the rated load is wear, not a fault — see the product safety page.
