Expandable backpacks give you extra room when you need it and pack down smaller for daily use. The range runs from the Coreva 1908 (22 to 45L) and the Zenith 22005 (25 to 35L) to the KAKA 2050, which goes from 36 to 56L. The Ontra 77115S is a slim expandable model for everyday use.
When expanded, some models exceed airline cabin limits, so check the measurements on the product page against your airline before you fly.

01
More room when you need it
Expandable backpacks start compact for daily carry, then unzip to add litres of space for the days you pack more. It's the simplest way to own one bag that works for both the commute and the trip.
02
One bag, two capacities
Keep it slim through the work week, then expand for a weekend away or an overnight. No second bag, no compromise — just more flexibility from the pack you already trust.
03
Pack light, expand later
Perfect for carry-on travel and changing plans. Pair the extra capacity with the laptop protection of our laptop backpacks or the long-haul features of our travel backpacks.
