We are stoked to get to try out this backpack. I love that it fits into it's own attached bag for easy storage or carrying when it is not in use. I was actually surprised by how large the backpack is once you get it all spread out.
The bag is very lightweight. It is definetly not meant for heavy duty hiking, but it is going to work great as a day hike bag and I love that it is made from waterproof material because we like to play in the river when it is warmer. The bright orange color will also help us keep track of it (and the person wearing it) in the woods. It is very comfortable and will hold a lot, but I wouldn't try to stuff it full because you may put too much strain on the zippers.
Overall I am very pleased with this bag and I can't wait for summer to get here so that we can get some real use out of it.
