This duffle is as large as it can be while still being acceptable as carry-on luggage. Suitable not only for air travel, it can also be used for car travel, field work, or a bug out emergency bag, to name a few. You can pack this bag full, head out for your next adventure and the chunky #10 zipper will not burst under strain. Snap the zipper protection flap in place to protect your belongings inside from whatever weather you may need to run through. The 1 ½’’ wide cotton webbing goes all the way around the bag to give support to your heaviest loads while the double layer bottom gives you extra protection against abrasive surfaces. Two exterior pockets help keep smaller items organized and easily accessible.
