How this catalog is kept

What we re-check, how often, and what to do when a figure here argues with the one at the till.

The prices

The catalog was last updated on September 14, 2026. Every price on this site comes from our own product data and is refreshed on a schedule rather than typed by hand. Prices move between updates, and the figure at the checkout is the one that counts: where the two disagree, the till wins.

A bag with no live offer is not shown at all. It leaves the shelf at the next update and comes back on its own when it is available again, so the count on a shelf page moves from one month to the next.

The figures on the cards

Three dimensions in inches, capacities in litres, bottles, quarts or pairs, compartment counts and materials are read out of our product data, never estimated. Where a figure is missing from a card, it is missing because we do not hold it.

The photographs

Every frame is looked at beside the bag it claims to show before it goes up. On this catalogue that turned out to matter: most of the secondary frames the brand publishes are advertising panels with slogans printed into the pixels, and none of those run here. What you see is the pack shot of the colourway named on the card.

The sources

Where a page here makes a claim that needs an outside authority, whether that is a child in an aeroplane seat, a loaded pack on a small back, or a bottle of polish through a checkpoint, the authority is named below with the date we read it.

Sources, opened and read on September 3, 2026

Flying with ChildrenFederal Aviation Administration. The safest place for a child under two on a US airplane is an approved child restraint system, not a lap, and the FAA strongly discourages carrying a lap child. A seat has to read "This restraint is certified for use in motor vehicles and aircraft", and one that cannot be secured properly in an airplane seat may be checked as baggage instead.
Flying with Children: CARES child aviation restraintFederal Aviation Administration. The strap-based alternative to a hard-backed seat is certified for children between 22 and 44 pounds and up to 40 inches tall, approved for every phase of flight and for aircraft only. It is not a car seat and does not replace one on the drive at either end.
Car Seat Use After a CrashNational Highway Traffic Safety Administration. A seat is to be replaced after a moderate or severe crash and never used again after one. The list of conditions that make a crash minor enough to keep the seat ends with a plain one: no visible damage to the car seat.
School Backpack Safety: Proper Fit, Smart PackingAmerican Academy of Pediatrics, HealthyChildren.org. A loaded pack should not weigh more than 15% of the child carrying it. Its bottom belongs in the curve of the lower back and never more than four inches below the waistline, straps should be two broad padded ones, and the heaviest things go closest to the body.
What Can I Bring: LaptopsTransportation Security Administration. Laptops travel in carry-on and checked bags alike. Outside PreCheck they come out of the bag and into a separate bin for X-ray, which is the entire job an opening angle has to do at a checkpoint.
What Can I Bring: Nail PolishTransportation Security Administration. A carry-on bottle falls under the 3.4 ounce (100 ml) rule. In checked bags the aggregate is capped at 2 kg or 2 L per person, with 0.5 kg or 500 ml per container, and the officer at the checkpoint has the final say either way.

Corrections

Wrong figure, wrong photograph, wrong sentence: pack@yorepek.org, with the page. We fix it and say what changed.
