Purchased this pack to carry our 1 year old on hikes. Used it every day while pregnant with our 2nd. So comfortable that I barely knew it was on. We have used this in rugged terrain as well as easy trail settings. Our son was so comfortable he would often fall asleep. Easy to adjust, and love the hydration system compatability. Makes it so much easier to stay hydrated. Plenty of storage compartments with more then enough room for drinks for the child, as well as snacks for the entire family. Easy to put on and take off by myself even with child in the carrier. I love the attached sunshade. No worries about carrying a sun shade that is not attached or no worries about forgetting it in the vehicle. Purchasing another one to carry our 2nd child. Can't wait to hit the trails again!
