EUC Paragon Red Hydration Backpack

Bought this water-carrying backpack decades ago from MEC when I thought I'd become a cyclist. I didn't. Used it a few times. It is in pristine condition. Pictures show the tube from my old water bladder, but only selling this backpack. 19 x 10 inches. Great for long walks or hiking, too. From a pet-free/smoke-free home.
