Whether it's an impromptu trip out of state or just a big day out the Osprey Transporter 40L Duffel consistently holds everything we need. This 40L duffel bag is built to be comfortable even while fully loaded. The tough outer shell means that even if we use the duffel as checked baggage we won't be needing to worry about our stuff. Made for a rowdy weekend or just a week-long getaway we constantly use the smartly sized Transporter 40L Duffel.
