Peak Design luggage sizes
Peak Design is a carry and travel gear company best known for its camera clips, straps, tripods, and modular packing and camera cubes, alongside a well regarded Travel line of bags. The Travel line centers on the expandable Travel Backpack, the pure Travel Duffel, and the hybrid Travel DuffelPack, all built with weatherproof recycled nylon shells and no wheels or rigid frames. This dataset covers the Travel line only, not the camera clips, straps, tripods, or packing and camera cube accessories. Peak Design publishes exterior and interior dimensions for every Travel bag in both centimeters and inches on its own product pages.
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.
