The back panel forms a gusseted, bellowing pocket for carrying a liquid-containing hydration pouch.

The corrugated hose 10 further has at least one bellows pocket 14 extending radially outwards in a circumferential manner in order to enable a balancing of the movement of the hose body 12.

The separating of the flow on the tearing edge 20 prevents the flow from flowing into the bellows pocket 14, thus creating a corrugated hose 10 that is easy to produce and has a low flow resistance.

According to the invention the hose body 12 transitions across a sharp-edged tearing edge 20 in the flow direction 18 in order to separate the flow from the hose body 12 in the bellows pocket 14.

The expandable back pocket includes themed stickers inspired by the pioneering video Dylan made for another 1965 hit, ''Subterranean Homesick Blues''.
