[40L Large Capacity - Perfect for Multi-Day Trips] MIZIKIRIN's large-capacity backpack combines stylish design with practicality. It can be used as a daily commuter backpack, a weekend getaway, or a 3-7 day business trip, covering all occasions. By opening the hidden zipper on the side, you can expand the capacity up to 40L. It compresses down to a lighter size for lighter days and offers spacious storage for heavier days. Its flexible shape allows you to freely adjust it to suit your needs. [Dual USB Ports] MIZIKIRIN's multifunctional business backpack features dual Type-C and Type-A charging ports built into the side. Simply connect your mobile device to quickly charge multiple devices, including smartphones and tablets, simultaneously. The ports feature a sealed dustproof and waterproof cover, protecting the interior from rain and dust and ensuring a clean and reliable connection at all times. This backpack's clever design allows you to quickly access charging without having to open your bag, whether you're waiting at the airport during a business trip, outdoors, or on a long commute. Keep your devices fully charged and never miss important information or moments. [Organized storage revolutionizes travel comfort] MIZIKIRIN backpacks offer "large-capacity scientific storage." The wide-opening clamshell main compartment allows you to organize 3-7 days' worth of luggage at a glance, just like a suitcase, making travel easy. Three independent functional compartments allow for smart use: Shoe bag: Completely isolates dirt and odors, keeping clothes clean. Wet pocket: Waterproof divider neatly separates wet items. Dedicated laptop storage pocket: Cushioned and quick access, it reliably protects sensitive equipment. The organized storage system transforms every trip into an efficient and comfortable experience. [Convenient for Carry-On and Security Checks] MIZIKIRIN's carry-on backpack features a separate laptop compartment that can be opened and closed separately. Passing through security smoothly without opening the main compartment is a breeze. It meets most airline carry-on baggage standards (compressed: approximately 45 x 32 x 18 cm, expanded: approximately 45 x 32 x 25 cm). Note: Dimensions and weight may vary slightly due to manual handling and measurement methods. The top and side handles allow for quick access to the laptop, even from overhead bins, cabin seats, and security bins on fully booked flights, reducing travel stress. This laptop backpack significantly improves the efficiency of your business trips and travel. Please note: Carry-on specifications vary by airline; we recommend checking before boarding. Water-repellent for lasting comfort: MIZIKIRIN backpacks are made with 900D Oxford film material and are treated with a water-repellent finish, so you can rest assured that they will withstand sudden rain or everyday splashes. Additionally, the 3D-structured back panel, thick shoulder pads for a perfect fit, and an adjustable chest strap provide ergonomic support, reducing strain even during long trips. The back is equipped with a luggage strap that can be threaded over the handle of a suitcase, making it ideal for business trips and travel. MIZIKIRIN's business backpacks are designed with efficient travel in mind. The large-capacity body expands flexibly up to 40L, and features a clamshell-style main compartment and separate shoe, wetsuit, and laptop compartments, allowing you to organize your luggage for 3-7 days. The carry-on size and separate laptop pocket allow for smooth security checks. It's packed with features to make every trip comfortable, whether you're on a business trip or traveling, including a Type-C/A dual USB charging port, water-repellent material, an ergonomic, comfortable carrying system, luggage straps, and a multi-handle.
