Very good Quality. No leaks

I ordered this hydration pack for short day hikes for the family knowing no one can backwash and I could put it in different backpacks easily. I tested it out at home before we are packing it in a backpack just in case it leaks as some other brands have in the past. I filled it very full with ice cubes (huge plus that I can fit my giant cubes in the hole so they last longer) and water and went about my day while drinking out of this instead of my typical water bottle. At first the bite piece seemed a little hard to get to open enough for adequate drinking but it kind of broke in and I got the hand of this one after a few more tries. The open and shut valve is easy to operate and convenient too as to prevent any leaking that could occur (I didn't have leaking myself). I was very very happy to have the large opening and fill spot though because I was able to get in there and clean the seam areas where being able to do that on other brands is a huge pain in the rear. There are two holes located at the top for attaching into a back pack so this will be a cinch to throw in on our hikes. The other great benefit is that its BPA free which is very important to our household. Overall I am very happy with this purchase!
