The HP Travel 25 Litre 15.6-inch Laptop Backpack in Iron Grey (6B8U4AA) is a one-bag travel backpack that carries a laptop of up to 15.6 inches plus clothing and gear for a weekend away. It holds 25 litres in normal use and unzips to expand up to 30 litres. HP designed it with a large number of organisation compartments and quick-access pockets inside and out, a tablet sleeve, lockable zippers and an RFID-blocking pocket to protect bank cards. Comfortable padded shoulder straps and a sternum strap spread the load on longer walks, and it has a carry handle. The external material contains 100% post-consumer recycled plastic and is water-resistant. The backpack measures about 320 x 440 mm with a depth of 170 mm, expanding to 245 mm, and weighs 0.86 kg. It suits frequent flyers, students and commuters who want a laptop bag that doubles as a carry-on. Packaging uses a recycled LDPE bag and recycled-paper tags. Colour: Iron Grey with dark grey trims. A Blue Night version is also available as a separate product.
