The Maxpedition IRONCLOUD is a large, rugged, carry-on friendly travel pack. Its large and securely lockable main compartment features an internal compression bib that holds the contents in place during travel, and fastens using high-quality YKK zippers with convenient positive grip pulls. An external padded pocket fits and protects a 15 inch laptop or tablet, allowing quick access without opening up the whole bag. The IRONCLOUD is also extremely portable, thanks to its triple carry system. It includes a side handle, backpack straps and a shoulder strap to give you plenty of carry options. It is made from a blend of 500 denier ripstop and 1000 denier nylon, making it highly durable and wear-resistant, and features an air mesh back panel for breathability while carried backpack-style.
