This is arguably the most popular hydration pack for people looking to save money. 4.5 stars out of 900+ reviews on Amazon, so most people like it. I have one myself. It gets the job done. Holds Water just fine, easy to fill up, has a cap at the spout to protect from dirt, all the goods. Doesn't look fashionable as some of the other ones but hey, $22 is a great deal. https://www.amazon.com/Mubasel-Gear-Hydration-Backpack-Bladder/dp/B015GONGTG/ref=sr_1_1_sspa?ie=UTF8&qid=1528207450&sr=8-1-spons&keywords=mubasel+gear+hydration+pack&psc=1
