It has a spring-steel perimeter frame that provides load support while also allowing the back panel to conform to your torso. The padded, mesh-covered straps, belt, and back are designed keep you cool and comfortable. The U-shaped panel opening makes it easy to access all your gear when completely unzipped. The top has a zippered pocket on the underside for your keys and valuables, and there are also zippered hipbelt pockets that let you access snacks and other essentials as you hike. And finally, it comes with a raincover that stows in its own zip pocket.
Promising review: "I absolutely love this bag. My family does Disney quite often, and we need to take special foods for my son. It has enough space for a small/medium thermal lunch bag, snacks, towels, rain ponchos, sun screen, first aid kit, hats, and everything else we need when walking in the parks. The main compartment can be opened from any side, which makes it easy for security to check when entering the parks.
The straps are comfortable, and the hip belt really does help keep things light. The compartments on the hip belt allow me to keep my phone and camera easily accessible.
I don't carry a hydration pouch, but I use the hydration tube hole for my USB cable, which connects to a battery pack inside the pack. This way, I can charge my phone, my wife's phone, and my camera throughout the day. It's a nifty little set up!
The best part is the price. Hands down, I would have paid much more for a pack with the same features, but I didn't have to." —Yadi279
