I've had 2 of these bags since Nov of 2017. I originally purchased them to move from one state to another and to use as luggage for travel. So far I have used them moving, camping: in the Sierra's, Cascade Mountains, the Olympic Mountains, snow trips to Whistler BC, and Methow Valley, they have traveled to China, Germany, Japan, Finland, Sweden, Norway, and many states in the US. My point is they have taken quite a beating, got wet, dusty, been in freezing temps, and no cracking, zippers are still perfect, the material is not damaged, etc. This hold up well and are tough. I love them, and have even used for trips to the shooting range, packed full of heavy things like ammo, weapons, etc.
