this is our backpack. or sea bag. or pack sack, out of durable original cordura (330den) main fabric, designed for bouldering, for example. the idea was to create a backpack that takes up little space but is still comfortable to wear. you can easily throw it into the crash pad without it getting stuck. or hang it comfortably over your shoulder if there's no more room in the back. you can fill it from the top, but you don't have to rummage around when you're looking for something, thanks to the zip along the whole length. small inner pocket for nail pinchers, lighters, knives and all the other essential small stuff plus small carabiner for your key ring. of course you can also combine it with our shoulder bag using the magnetic closure. or attach one of our brushes. or our small climbing chalk bag, but more on that a little later.
