If you're looking for instructions on how to use a Karrimor hydration bladder. Here are a few simple tips to get the most out of your hydration bladder.  First, make sure that the reservoir is properly filled with water. You can do this by unscrewing the cap and filling the bladder to capacity. Once the bladder is full, screw the cap back on tightly. Next, find a comfortable position for the bladder. The best way to do this is to place it in a backpack or camelbak so that it sits snug against your back. This will help distribute the weight evenly and prevent the bladder from bouncing around as you move. Finally, drink from the tube as needed to stay hydrated throughout your activity.
