The water spout is right at your shoulder (and it doesn't leak thanks to its slide lock).
It's made of 600D rain resistant material with SUPER comfortable and adjustable shoulder and waist straps.
The back even has a unique, breathy design which allows air to flow easily through, preventing your back from getting too sweaty.
What's even cooler is that these backpacks are environment friendly. Since you can reuse the water bladder for every hike, you don't have to buy any more plastic water bottles. Just fill up the bladder and you're good to go. You can even slip some ice in the bladder to keep your water cool.
