Bag spec source: peakdesign.com · accessed 2026-07-09. Airline limits come from each carrier's official baggage page; open an airline above for its citations. Policies change, so verify a borderline case before you fly.
Peak Design lists a separate exterior (external) and interior dimension set for each bag, given in centimeters with the inch equivalent in parentheses. The Travel Backpack sizes are expandable, so the page gives a standard unexpanded exterior and an expanded exterior; the exterior field here stores the standard unexpanded size and expandedDepthIn stores the expanded depth. Travel Duffels do not expand, and none of these bags have wheels or a rigid frame, so the published exterior is the soft bag body.
