The BÉISics Duffle in BlackRelationships are complicated, your overnight bag doesnt have to be. From situation ship to an extended weekend stay our BISic duffle doesnt judge. To the outside eye we kept it minimal (no one needs to know what youre up to) but in reality, this bag has a lot going on. With a removable shoulder strap, key leash, trolley passthrough, and a wipeable interior this duffle allows you to choose your own adventure.
