I feel like I bought maybe the best possible duffel bags out there with this model and brand. These are a very durable and useful bag. After getting the XL Green came back and got Large Blue.  In the XL size, you can fit a sleeping bag, camp pillow, multiple small toiletry bags, shoes, and bunch of clothes in.  Its probably all you really need.  In the Large you can get either a weeks worth of clothes, or fill it with other gear for car camping.  The handles can also be worn as a sideways backpack if you need to free your hands to carry other things. The fabric feels like it will last forever.  We all like the green best though, they seem to blend in, hold so much and work so well for men or women and are soft and collapsible. My opinion of Eagle Creek products has become very satisfactory after this purchase.
