Using the HydraPak 2L Seeker is easy. First, open the 42mm screw cap and fill it with water. You can use it as it is or attach it to your backpack using the top and side attachment points. When you're done with the water, you can collapse it down and put it in the included storage bag. If you want to use it as an ice pack, just freeze it. For a warm pack, fill it with hot water. Remember, don't overfill it beyond the 2 - litre capacity. Also, when using it with a water filter, make sure it's properly attached. To maintain it, clean it regularly with mild soap and water. After cleaning, let it dry completely before storing it. This will help keep it in good condition for your next adventure.
