With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

The Beast Bergan - (MultiCam & J1K)

Instead of fixed side pouches, the Beast comes with mesh bladders and fixings that are compatible with issues PLCE side/rocket pouches. Side compression straps are also a new addition.

The Beast is a 125ltr capacity rucksack designed for wearing with belt kit. (With rocket pouches this goes up to a huge 150ltr capacity).

The Bergan sits on an external high density polymer frame to ensure maximum air flow around the back area.

An inherent problem with external framed bergans is that they can squeak under load. We have now incorporated anti squeak pads on the webbing straps to eliminate this problem

The Bergan's’ profile is low in height yet wide enough to cope with large volumes of kit needed.

JayJays padded wider shoulder straps are fitted for comfort due to the amount of time the Bergan is worn and the loads carried.

Multiple pouches on the front and sides allow the user to access kit that is used frequently without having to open the main compartment of the Bergan.

Developed over 3 years with feedback and user trials from some of the best Jungle Warfare instructors in the business. This truly is one of the best all round Bergans for todays soldiers.
