One bag. A full week. The DopplerMatte Weekender is a 36L duffel for trips that outgrow a carry-on but don't warrant a suitcase. A waterproof membrane shell and matte waterproof YKK zips seal out rain and transit, while a ripstop lining holds structure without adding weight. At 20.5" x 10.25" x 10.65", it stows overhead and rides on a roll-aboard handle. Clean on the outside. Purpose-built on the inside.
