I'm taking a weekend trip out of Newark to Las vegas in two weeks. I just bought a black Elisha and love it. It rests especially well on my shoulder compared to all my satchels. My only concern is the opening at the top. the magnetic closure is slightly defective. (I bought it from AE at 30% off and there are no more left.) i think it would be difficult for someone to stick their hand into the narrow opening when it is on my shoulder. would i be better off with my medium black bianca thatt zippers and has a turnlock? the elisha would really free up my hands for my suitcase and carryon. i do worry about pickpockets. Any advice?
