Travelers who need serious gear protection, this HAZARD 4 carry-on is built like a tank! The 2020 version has been upgraded with Cordura fabric instead of rubber textiles for better durability, and tricot interior liners that work with hook-fastener dividers. The external dimensions are about 22.8x14.2x9.1 inches - perfect for TSA overhead bins on most airlines. What makes it special is the wide wheel base with oversized all-terrain wheels that roll smoothly on everything from airport floors to cobblestone streets without tipping over. There are MOLLE and velcro areas on the outside for attaching additional gear, plus a 3-D rubber ID window included. The padded laptop sleeve loads from the outside and fits up to 17-inch laptops, with multiple organization pockets throughout. The new patented roto-locking buckles are super secure, and they've simplified the decorative trim to reduce weight. This isn't your typical fashion carry-on - it's built for photographers, journalists, contractors, or anyone who needs their gear to survive rough handling. The 1000D Cordura material can take serious abuse without showing wear. Seriously, if you're tired of flimsy luggage that falls apart after a few trips, this is the 4x4 equivalent of carry-ons that will last for years of hard use.
