Osprey lists pack dimensions on its product pages as height by width by depth, in both centimeters and inches. The centimeter values are the consistent primary figures and Osprey's inch values are rounded and vary in axis order between page versions, so entries lacking a clean published inch triple were converted from Osprey's published centimeters at full precision and rounded to one decimal. Dimensions for the Farpoint and Fairview 55 and 70 packs are for the main pack body and do not include the detachable 15L travel daypack, per Osprey's own note, while the stated volume does include it.
