Tried to mount on my 35 spare mounted on the rigid rack. Very, very difficult and barely fit. Clasps are super difficult to clip and un lip. Tightening straps one barely on, straps would not tightened unless I again removed the bag. For a strap on bag it should not be this difficult. I erred on the safe side and removed it due to safety concerns. Not great for a off-road tote but make a decent laundry bag for the house. I would not recommend this particular product for off raiding storage. I only gave it two stars due to the bag construction. Look elsewhere and save some money. I did end up using a old military back pack which worked better and easy to mount and take off. Clasps were easy as well. Another waste of dollars on a substandard product.
The only thing I can complain about is the draw string doesn’t really work.
