Expandable 19" Vacuum Backpack — Waterproof Travel Bag with Electronic Pump & Anti-Theft Lock for Business & Leisure

Large, expandable carry: This 19" travel backpack offers a roomy, expandable main compartment with organized, multi-zone storage. Inside you'll find a wet/dry separation plus divided pockets to keep tablets, phones and books tidy and accessible. Vacuum compression system: Built with a dual-shoulder compression vacuum design and an exhaust valve to remove air and create more usable space. You can expel air manually or use the supplied electronic vacuum pump to minimize wasted volume. The pump supports inflation and vacuuming and comes with multiple nozzle attachments for different uses. Reliable waterproofing: The pack uses a multilayer waterproof approach — a waterproof oxford outer shell combined with an inner vacuum compression sealing bag made from TPU. Even if the bag is submerged, the contents remain dry. Customs-friendly anti-theft lock: Features a customs combination lock that can be opened with a special customs key for inspections. The combination can be set independently and is simple to program, providing extra protection for your belongings. Comfort and fit: Shoulder straps are padded with three-dimensional sponge for reduced back pressure and improved breathability. Adjustable fixing straps help the bag conform to your body and let you secure the pack to a trolley case. Practical details: Includes a hidden zippered pocket ideal for a cell phone and side pockets sized for mugs. The design suits students, business travelers and leisure users, and the stylish appearance works well for both men and women.
