One week into using this bag it became harder to pull. One wheel had started dragging on the side after the axel slightly bent. The plastic wheel is shaving itself down as well so it leads me to believe the wheels themselves may not hold up over rough terrain. While this is a very nice large bag the build makes it questionable for anyone who may be taking this somewhere serious.
Blackhawk is currently working to get me a replacement and the rep there seems very helpful.
Pros: Very large, seems sturdy.
Cons: Wheels are undersized and axel broke.
