Every bag in this category was picked against one test: packed for a real trip, does it stay inside the 7 kg hand carry limit used by PIA (widely reported), SereneAir and AirSial (officially published) and the Gulf carriers in economy? That means light empty weights — soft bags around a kilo, trolleys kept honest — and sizes at or under the common 55 x 40 x 20 cm cabin standard.
If you are new to the maths, read the 7kg hand carry guide first: the bag itself is part of the 7 kg, so a kilo saved on the bag is a kilo of clothes gained. Sizes and weights are stated on every product page so you can check against your airline before ordering.
