FAQ
Yes. Its slim silhouette and adjustable rolltop make it a strong cabin-friendly choice. It typically fits under the seat or in the overhead compartment, and it also slides onto your suitcase handle thanks to the luggage sleeve. Always compare our dimensions (40–52.5 x 30 x 17 cm) with your airline’s rules to be 100% sure.
Absolutely. The back panel includes a padded, fleece-lined sleeve sized 31 x 27 cm, designed for laptops up to 14” (including a 14” MacBook). It keeps your device protected and close to your back for better comfort.
Yes — the outer fabric is water-repellent and ideal for everyday drizzle, splashes, and wet commutes. For heavy downpours or long exposure, treat it as “splash-proof” rather than fully waterproof and consider adding extra protection if needed.
Totally. You get multiple internal pockets and compartments, including mesh organization, zipped sections, a dedicated bottle holder, plus travel helpers like a wet bag and a removable liquid pouch — so small items don’t vanish to the bottom.
