These cases come with two carrying straps and can be ordered with the case cover at extra cost.  I don’t think they have a Spanish distributor yet so I bought mine from the UK dealer.  They are very light and certainly solve two of the problems with guitar cases.  Most other cases will pass the shock of a drop straight to the guitar but these don’t have any firm contact points with the guitar so most of the shock will be absorbed.  The crush strength is very good too although something very heavy will still flatten it.
