Backpacks are great. So are messenger bags, sling packs, briefcases, and clutch bags. We love (and own) all of those, but if you’re a minimalist packer, you really only need one bag to carry around your everyday gear. That’s why this rugged pack can be used as any of the above thanks to a thoughtfully-designed 5-in-1 carry system. The thing is made from indestructible, waterproof ballistic nylon, with tons of pockets and packing cubes for ultimate organization, and built-in compression straps for easy loading. It’s also got a TSA-approved Wooltech laptop sleeve, and more internal accessory pockets made of the same material. The end product is a ridiculously versatile, mind-blowingly tough bag made to go with you everywhere.
