38 l travel backpack INUK 38L for Men & Women, Water Resistant Laptop Backpack Hiking Daypack, Eco Friendly Made from 32 Recycled Plastic Bottles with Safety Whistle & Fidlock Magnetic Buckle, Black packing four or five days into one carry Carry-On Travel Backpack (38L) –

However, some reviewers didn't realize that this item comes with a faux zipper

Superior materials for a superior product

(By comparison, the 100-liter Black Hole only weighs 7 ounces more.) That said, it still feels reasonable when you factor in the metal hardware, multiple carry options, and packing accessibility

the water bottle pockets on each side of the pack are made with the same 420-denier nylon as the body of the backpack and cinched with elastic

The top pocket is surprisingly spacious and I can fit a large amount of stuff in there
