For its price and durability, it is very good. Be careful with the capacity it states because it is misleading, and the size is not what you might expect as it is incorrect. I bought the bag with a capacity of 18 liters, and in reality, it is much larger at about 35 liters, according to the dimensions it states (Height 45 cm, Length 34 cm, Width 23 cm). 45*34*23= 35.190 ~ 35 liters. The truth is I didn't want it to be that big since it is like a sack.
