It's important to carefully choose the gear you carry on a daily basis, but it's also important to consider how you carry it. Clipping items like your folding knife and flashlight to the hem of your pocket provides quick access, but also takes up valuable pocket space and isn't exactly discreet. Add in a few larger EDC items, like a tourniquet, hemostatic gauze, fixed blade knife, and/or multi-tool, and your front pockets will quickly end up stuffed full. And nobody wants to walk around town looking like knock-off version of Adam West's Batman with a utility belt full of exposed gadgets.
Holster manufacturer PHLster came up with a smart solution that incorporates modular gear storage into an appendix inside-the-waistband (AIWB) setup. Many of us already carry a concealed handgun and extra magazine in this position, so it makes sense to tuck in a few other essentials as well.
This system is called the PHLster Flex, and it's basically a piece of pre-cut polymer material with holes, slots, and attachment hardware. It can accomodate belt loops or hooks on either side, plus a holster and any other gear you may need to carry. We could see this being especially helpful as a way to carry emergency medical gear like a TQ, Quik Clot, or an Epi-Pen while retaining pocket space for other daily-use items.
