The Viper Security Jacket is a great bit of kit for all those involved in contract security work - especially door supervisors.

It has panels with 'security' written on them on the front and the back. The back one is large. These panels can then be concealed with zips, which mean you can wear it home after work or off duty. The sleeves can also be unzipped to create a badged body warmer. The jacket has a velcro panel on the left chest to attach your the logo of your company or individuals' name tags. Shown here with a detachable Viper logo.

If you're involved in contract security work as a door superviser or in event security, you'll need one of these as much as your SIA license.
