Expandable 19" Waterproof Vacuum Travel Backpack with Pump — Anti-Theft Combination Lock for Men, Business & Leisure

Large-capacity expandable travel backpack designed to adapt to changing storage needs. The interior is organized with multiple compartments, including dedicated wet and dry zones and pockets sized for tablets, cell phones and books, so items stay neat and accessible.

Dual-shoulder vacuum compression system lets you remove air through an exhaust valve to gain extra space; you can expel air manually or use the included electronic vacuum pump to minimize wasted volume. The pump supports inflation and degreasing and comes with various nozzles for different uses.

Built with a multi-layer waterproof construction: an outer waterproof oxford fabric shell plus an inner vacuum compression sealing bag made of TPU fabric — even if the entire backpack is submerged, clothes inside remain dry.

Security features include a customs-style combination lock that can be opened with a special customs key after inspection; the lock allows you to set an independent password with simple setup steps. Versatile for many occasions — college, short or long trips, and business travel — with a fashionable look suitable for men or women.

Comfort and convenience details: shoulder straps padded with three-dimensional sponge for reduced back pressure and improved airflow; fixing straps to keep the pack snug to your body and to secure it to a trolley case; a hidden zippered pocket for phone storage and side pockets for mugs.
