Are we going to a remote campsite for a weekend or a whole week? We trust the Deuter Aircontact Core 65 10L backpack. This backpack uses internal and external pockets that keep us organized and on the move. The true function of this package is centered on the X-frame design and Active Fit adjustment. This combination ensures that no matter we know how heavy this backpack will be loaded that we can comfortably place it on our back.
