The NOBULL Duffleback is our all-around backpack. But it's better than a backpack. Carry it on your back, open it like a duffle, and get the best of both worlds. Keep your essentials safe and dry with a waxed canvas, water-resistant exterior. And keep the important stuff extra safe in padded internal compartments. There's even a drop cushion, so when your bag hits the ground, your laptop doesn't. Bottle pockets, external pockets for the little things, and a roomy interior for shoes, a towel, and more protein bars than any of us need. Plus, weight distribution that won't trash your back and molded support so you can carry all day. It's the gym bag we always wanted.
