"The Eagle Creek No Matter What 110L Duffel Bag swallows more gear than its folded-up footprint suggests, then packs back into its own zippered pocket once the trip is over. Recycled 600D polyester ripstop shrugs off the scrapes and damp that come with getting tossed in a truck bed or hauled across a dock, while lockable zippers and reinforced lashings keep a full load cinched down. A trolley sleeve on the back slides over the handle of rolling luggage, so it rides hands-free through the terminal instead of becoming a second bag to track. What Our Gearhead® Experts Are Saying:""I load this past what looks reasonable for a weekend and it still folds flat into its own side pocket once I'm home and it's empty.
