The Flow Motion System Works!

"The pack hugs the back closely and moves with the body without the feelings of restriction and discomfort. Stability is much better than with an ordinary pack on. I was skiing down from Cairngorm in a high wind; conditions were icy and darkness was falling – the pack was like a limpet, not swaying or moving at all, yet I had complete freedom of arm and shoulder movement."
