Hi Everyone, I use a 5.11 Tactical All Hazard Prime as my EDC Backpack; although a bit heavy. I need to fly a lot and it seems like that this bag raises the eye bro of the Security staffs and they go through a lot of scrutiny watching the lots of MOLLE web. My friends crossed the same terminal with bigger Jack Wolfskin Backpacks without any hassle. Hence I was planning for a new Backpack for my travel purpose without raising any issue with the Security Officials. So far my picks are 1. 5.11 Tactical Covrt 18 2. Goruck GR2 40L 3. Camelbak Urban Assault (Redesigned) Any first hand experience an advice are highly appreciated. Thanks in advance.
