Cool color. Would prefer the top handle to be separate from back straps, as lifting on handle causes straps to pull away from pack and interfere with legs while walking. The disc compartment cover is tricky to stow when open for use. Some suggest rolling it up, but that doesn't stay in place long. Better solution is to fold it into the disc pocket (which can still be used for storing a disk). Almost a homerun.
A label addressing flap stowage would be good. Side pockets are deep and can accommodate a long retriever, which is why I bought it. But, the weight of the retriever inevitably pushes the zipper down, exposing it to falling out of bag. I had to fashion a clip using a baby carabiner to keep the zipper up. Strapless bottle holder is nice. Strapped chair holder is nice. Firm bottom and sides are great for stability on uneven ground.
