BC2 Backpack Motion System. Backpack featuring a revolutionary carrying system.
Congratulations on your purchase of an Ergon BC2 Backpack. The backpack features a unique system, made up of a load bear-
ing frame and a ball joint. It provides a previously unachievable level of comfort.
Please read the following instructions carefully. They will describe precisely what makes the Ergon Backpack Motion System so
unique, and will set out the functions of the individual components of the system. It will also explain how to set up the system
correctly for you as an individual. Instructions are also included for cleaning and looking after your Ergon Backpack Motion System
to ensure its long service.
The Ergon team wishes you a lot of fun with your backpack.
1. Ergon's Backpacks are not worn in the same way as a traditional backpack.
The fitting of a traditional backpack is achieved through the tightening of the shoulder and hip straps. These straps are attached
statically to the bag itself. Once the backpack is 'fitted' it actually restricts your movement considerably. The weight of a traditional
pack is carried from the top, hanging from the shoulders. Breathing is also restricted by the hip belt, which usually rides high and
is fastened across the stomach.
An Ergon Backpack is constructed differently, using a number of components. These parts make up a unique system which
solves the problems of a traditional backpack.
1: The Frame - sits on the hips and transfers up to 80% of the load to the area of the body's natural centre of gravity.
2: The Flink
Ball Joint - isolates the shoulder straps from the carrying section of the pack.
®
3: The Shoulder Carrying System - adjustable to fit the length of the users back it stabilises the pack on the users back.
2. The function of the backpack components.
Frame
The hips are the body's ideal load bearing structure - not the
shoulders. Ergon's specially formed Profax PP Frame ensures
an even and equal transferral of the load to the hips. This
relieves the shoulders and spine. This distributes the
weight perfectly when the hip straps are about
+/- 3cm / 1 inch from the top of the hip bones (not on
the stomach). Maximum recommended load: 6 kg / 22 lbs
Flink
Ball Joint

Using the Flink
ball joint system to isolate the shoulder straps
®
Ergon Backpack Motion System backpacks allow for a new
level of comfort. Any load which is on the shoulders is evenly
distributed. This innovative construction is extremely comfort-
able and is very good for your back. The isolation provided
by the ball joint means that your shoulder movements do
not cause the hip belt to ride up. This prevents unnecessary
energy loss and the load stays put.
