Notes from our data check
Brand specs: 'Dimensions 19.7" (w) x 12.6" (h) x 7.9" (d) | 500 (w) x 320 (h) x 200 (d) mm'. It is a horizontal convertible travel bag (backpack, shoulder or hand carry), so Tom Bihn's 'width' is its longest side and is stored first. Weight by fabric: 1050d ballistic '2 lbs, 14 oz / 1295 grams'; 630d ballistic '2 lbs, 9 oz / 1170 grams' (the current 'Ballistic' colourways; stored, 2 lb 9 oz = 2.56 lb); 420d Spectron '2 lb, 7 oz / 1090 grams'. 'Volume 30 liters / 1830 cu. in. (ASTM Standard Measure)'. No laptop compartment (reviewers note this), so laptopIn is null. Brand: 'meets most requirements for North American regional commuter jets and intra-European flights'. $345 for every colourway; several are sold out. Synapse 25 (named in the brief) was dropped: Tom Bihn calls it a personal item. Amazon not checked (Tom Bihn sells direct).
