Available in 35L or 51L, the Kingkong Core Duffel sure lives up to its beastly name thanks to its near-indestructible 600D polyester outer with heavy duty hardware and webbing and slots to stash the likes of laptops and water bottles. Military inspired, it wouldn’t look out of place strapped to the outside of Humvee or M1 Abrams tank. Get it in in Charcoal, Desert, or Black.
