This cute vinyl cover cap resembles an acorn hat. Using smaller items or transferring only the amount you need into small containers for hiking trips is the first step to reducing weight. However, it would be counterproductive if it made things difficult to use and left you wondering, "Where did it go?" Adding this one item to small bottles and other items can quickly transform them into "hangable containers." By attaching them to the key loop of a sacoche or other bag, you can reduce stress while hiking and prevent them from getting lost.
