This "IKYWT Airback Backpack, 60L Expandable Vacpack Backpack Vacuum Compression" is a very interesting and innovative backpack. I was very surprised by its build quality and features.Here are just some of it's features:- Tough exterior material - made with high-density oxford fabric that is water resistant- Multiple pockets to help organize your cloths, toiletries and computer accessories- Innovative vacpack compartment that lets you compress your cloths with an "air-tight" compartment and one-way valve. Just one note on this is that it is not completely "air tight" after compression it does let air in slowly. The put this in their advertisement to address it: "【Important Notice】To avoid the stubborn creases caused by long term compression, the sealed compression bag is designed to bounce back extremely slowly and then clothes will be wrinkle-free"- Can carry a 17" laptop - large laptop capacity- Comfortable handles and shoulder straps and the back part allows air flow between your back and the bag for comfort.- Strap to carry on your carry-on roller. The only thing I didn't care for here is that it carries the bag sidesways which might not be the best for access to the compartments and your drink holder.- Small hidden compartment on the back where you can put your passport, etc- Expandable thermos/drink holder- Locking compartment for you laptop- It even has a safety whistle built in!This is a well-built backpack with tons of features and large capacity that can carry enough stuff for a weekend trip all in one bag.

Could store more than a carry on luggage!
