A PATENTED & PATENT-PENDING PROTECTED INVENTION WITH REVOLUTIONARY TECHNOLOGY AND A HERITAGE FROM MOUNTAINEERING, YACHTING AND THE MILITARY

 

THE EXPETOSYSTEM®, OUR ORBITAL TRAPEZE TECHNOLOGY

What makes the Wolffepack® unique is its orbital trapeze technology that frees your pack to swing around your body. We call this the expetoSYSTEM® (from the Latin, ‘I reach’).
This technology is protected by UK granted patents and multiple UK, US, EU and international pending patent and design applications. We are continuing to file new patents as we improve the technology.
The revolutionary design connects the bag to the straps on your shoulders with super strong cords. These cords can be released to allow the pack to separate from the straps and then revolve around the body from back to front.
Inspired by technology in the world of yachting, we designed a totally new rope locking and releasing system to enable the user to move the bag where and when they choose.
We wrapped this together with custom ergonomics and leading edge backpack design to deliver a great user experience. This creates a whole new world of functionality and flexibility in using the backpack.

HIGH STRENGTH MILITARY-GRADE MATERIALS


The super-strong cords contain Dyneema®, renowned as the world’s strongest fibre. It is 15 times stronger than steel. It’s a light material, called UHMWPE (Ultra High Molecular Weight Polyethylene), but is used by the military for body armour and bullet-proofing. The maximum total cord load is around 300kg. This type of cord has been extensively used by mountaineers for its outstanding performance.

DESIGN INNOVATION FOR A BETTER EXPERIENCE

Magnetic Magic: We’ve paid close attention to the details of the Wolffepack® and the expetoSYSTEM® to give the best user experience. We've used the most innovative magnetic catches on the market to give a satisfying and secure feeling to the handle.
Back Protection: Integrated into the harness that remains on the user's back is a panel that offers additional back protection in dynamic situations.
Ergonomic Refinement: Over the course of many, many prototypes, the finished solution has been carefully refined. We have used the latest 3D printing technology to accelerate the prototype development and improve the final product, for example in the ergonomic shape of the handle.

TECHNICAL PERFORMANCE BENEFITS & DETAILS

Being engineers, we've analysed carefully the performance and benefits of the expetoSYSTEM®. At the risk of sounding like nerds, we've even quantified the performance benefits to using the expetoSYSTEM® compared to a typical conventional backpack, based on empirical measurement and fundamental physics.
90% FASTER: according to our bench tests comparing the average time taken to access a single object from a conventional backpack, relative to the simple operation of the expetoSYSTEM®
90% LESS EFFORT: according to our calculations the energy expended in accessing a Wolffepack® backpack is a fraction of that using a conventional backpack (based on a 80kg user lowering a 5kg backpack to the floor for access)
INVENTION PROTECTION: For the intellectual property nerds that like to know the details, the Wolffepack® and expetoSYSTEM® represent an invention that is protected by granted UK patents, UK, US, EU and international pending patent and design applications including GB2511573, WO2014/135894, GB1402768.4, GB1412859.9, US29/499,307, RCD 001403745-0001 and by UK and EU Unregistered Design Right and/or copyright. Wolffepack® and expetoSYSTEM® are also registered trade marks.
