TIGERNU B9831 Expandable Vacuum Compression Waterproof Travel Backpack with Pump

Redefine how you pack for long-haul business trips, international flights, and weekend adventures with the incredibly advanced TIGERNU B9831 Vacuum Travel Backpack. Engineered for frequent flyers and minimalist travellers who want to avoid check-in luggage fees, this high-performance rucksack features a built-in vacuum compression system. It completely eliminates the struggle of forcing bulky winter garments or soft items into a standard pack, compressing your gear down to maximize internal space.

The defining highlight of this rucksack is its integrated vacuum compression zone with a companion inflation pump, allowing the bag to expand from 27L to 37L. By using the pump to extract trapped air from your packed clothes, you can reduce their physical volume by up to half. When combined with the zipped 6cm depth expansion system, this daypack transforms from a standard commuter bag into a massive travel fortress that matches the packing capacity of a 20-inch trolley suitcase.

• Vacuum Compression Technology: Built-in airtight compartment paired with an inflation pump to shrink clothing volume down effortlessly.
• 27L to 37L Zipped Expansion: Unzip the rear expansion track to instantly gain 10 litres of packing space for longer holidays.
• 180° Flat-Opening Layout: Main cabin unfolds completely flat like a traditional suitcase for stress-free packing and airport tech inspections.
• Dual Material Protection: Built using heavy-duty, water-repellent Nylon Foam (Black) or rugged Composite Fabric (Blue) to block heavy rain.
• TSA-Approved Customs Lock: Integrated mechanical combination lock that secures your zipper tracks firmly against transit theft.
• On-The-Go USB Port: Features an external charging interface so you can top up your phone battery easily while walking down terminals.

The TIGERNU B9831 fixes the common issues of large travel rucksacks that sag awkwardly, strain your lower back, or let wet swimming gear ruin your clean clothes. It features a specialized wet and dry separation bag alongside a dedicated mesh zip layer to keep your toiletries isolated. With tuck-away arcuate shoulder straps, a reinforced chest buckle, and dual vertical/horizontal handles, you can switch from a comfortable rucksack to a sleek hand-carry duffle bag in seconds.

Depending on your choice of colour, this unisex bag weighs between 1.27kg and 1.51kg when empty, keeping its crisp, professional silhouette under heavy loads. The rear panel is lined with a breathable honeycomb air cushion to encourage ventilation against your back, paired with a heavy-duty trolley strap that slides easily over suitcase handles. If you want a hard-wearing, secure, and truly revolutionary bag to compress your travel footprint, this vacuum rucksack is built to deliver.
