I have the old original RIBZ front pack still in the back of the cupboard, the newer version seems to have the improvements the old version desperately required such as removing the incredibly annoying exposed hook velcro belt and noisy materials. Even then its usefulness for me is somewhat limited, the main drawback is that the front pack is quite uncomfortable to wear when fully packed out and eventually leads to overheating in warm weather and it interferes with any main pack that I have. I also don't particular like the restricted feeling it gives when wearing a backpack. For cold weather use a good jacket with large front pockets is again much more comfortable i.e. the classic British Army smock or even a Laksen Goretex Shooting Jacket.

It is also very expensive i.e. a complete Osprey LBE Assault MOLLE vest pack can be had for £30.

It does have its uses though as a cheap (expensive) and cheerful fishing vest rig.
