Great day pack
Me and my sons were in Zion, used the pack for the four days we were there. I loved the hydro pack, the backpack was able to hold extra clothes for everyone, rain jackets, food and camera equipment for all of us. Hiking with a 4 and 6 year old, they are always asking for food or something that is inside the pack, I found that it was easy to access all areas within the pack.
The pack road great on my back the air flow design made a huge difference on the hikes.
This was the first trip that I was able to use the pack, but so far I love the pack and its design plus the name stands for quality.
Hope this was helpful.
