Can you help me find the quintessential duffel bag?

Can you help me find the quintessential duffel bag?

I looking for the quintessential duffel bag. I want it to be large, but no larger than 100 liters. I looking for a bag with shoulder straps, like those found on a backpack. The bag will be used for car camping, airplane travel, and international travel. Lockable zippers would be nice. A bag that is weatherproof is also important. I have in mind The North Face Base Camp Duffel Bag or the Black Diamond Huey Duffel Bag. Thank you very much for your help! Arek Ashland, WI
