The H.V.C.D. High Visibility Convertible Dangler is a concept CLOUTAC worked on for about a year. Its design is based on the concept of fitting a large amount of items into a bag with a transparent window.
Its first use is as a sub abdominal bag to be used on your plate carriers using the velcro flap. It can fit 3x556 magazines and maybe 3 bottles of bang energy.
Secondly, it can be used as a waist pack or cross-body pack using the attached strap once you fold the velcro flap inside the pocket designed to hide it. It's a super quick process and can be converted in seconds. It has 2 mounting points to attach the pack either hanging or straight on. The included Siamese clips and Hypalon webbing makes the system super tough and secure while giving you a large range of motion.
The hidden pocket used to fold the velcro flap away can also be used to store flat items such as phones, cards, passports or $$$😉.
