"The Patagonia Black Hole 70L Duffel Bag sits in the sweet spot between a weekend bag and a rolling suitcase, with enough room for a week or more on the road and still light enough to carry off the plane and onto a bus. The TPU-film laminate bonded to the ripstop shell gives the bag its structure and resistance to the kind of abuse that happens in cargo holds and overhead bins. What Our Gearhead® Experts Are Saying:""I reach for the 70L when a trip runs longer than a long weekend. It swallows a week's worth of gear without needing wheels to move it."""
