We have a backpack hydration pack that is about 30 years old. The tube from the reservoir to the delivery mouthpiece has discolored and looks terrible. It had to go, but we didn't want to purchase a completely new backpack and hydration unit. The new hydration pack from Outdoor products is beautiful. the tube is clear, it is easy to fill and access. It also has an "open and closed" setting on the mouthpiece. My spouse had a stroke and her right side is limited. We hand the backpack on the bedside commode where the delivery tube is easily reached by her when she need water in the night. Thank you.

good product
