Ich tauche die D7/300 bar mit einem 40 lbs Evolve. Die Päckchen liegt super auf dem Rücken und ist trotzt leicht höherem Gewicht angenehmer zu tragen als meine zuvor genutzt Mono 12/300 bar. Das ich jetzt ein klein wenig mehr Luft dabei habe stört mich nicht wirklich ;-)
Die Ventile sind wirklich sehr leicht zu bedienen!
