Dan-Pak Plurmaid Hydration Backpack

It looks just as cute and stunning irl

I haven't used the original bladder yet but I can imagine it would be difficult as the cap/opening is smaller than anything I've used so far. There's no handle or anything to hold it up while you are filling it. Therefore, while I love the backpack itself, I don't want to risk any mishaps and decided to invest in a higher quality water bladder and swap it out. Otherwise, this backpack is perfect :)
