Weight varies slightly by series, so you always know exactly how much packing room you have. The H6 ranges from 3.7kg (Essential and RE) to 3.9kg (GO Series) and 4.1kg (Pro), while the H7 spans from 3.8kg for our ultra-light Air Series up to 4.7kg (Essential, RE and GO Series) and 5kg (Pro). With the standard 23kg checked baggage limit, that leaves you anywhere from 18kg to 19.3kg of actual packing room, depending on your model. All cases are made from premium German polycarbonate, one of the lightest materials in premium luggage, so you never sacrifice durability for weight.
