🧳 【Flexibility with Expandable Functions & Carry-Ons】
Increase capacity in one step
Simply open the zipper to expand the gusset by 5cm, increasing the capacity by 20% from 40L to 49L! This bag can easily accommodate souvenirs or sudden increases in luggage, reducing the stress of traveling.
Carry-on size
With external dimensions of 54 x 36.5 x 23 cm (+5 cm when expanded), and a total of 113.5 cm across, it meets airline carry-on baggage standards. It's perfect for domestic trips of 1 to 3 nights or day trips.
High-quality body and reliable YKK zippers
Lightweight and durable hybrid material
The hard body is made of a combination of lightweight, shatter-resistant ABS resin and impact-resistant polycarbonate (PC). Corner pads provide excellent protection from impacts during transport.
Smooth and durable YKK zipper
The main zipper is made by YKK, a proud Japanese manufacturer. Its smooth opening and closing and high durability allow for peace of mind even with heavy loads and external shocks. It can be used comfortably for a long time.
🧳 [Ultra-quiet casters & 3-stage carry bar]
Quiet and smooth movement
The combination of dual-wheel casters and silent tires reduces noise by approximately 30%, allowing for 360-degree rotation and smooth, quiet travel on any surface.
Carry bar that can be adjusted to your liking
The lightweight aluminum carry bar can be adjusted to three different heights with a single push, making it comfortable to use according to your height and the situation, reducing the burden of moving around.
🧳 [Organized interior and TSA lock]
Store your luggage neatly
The U-shaped compartment is made of soft, comfortable polyester fabric, making it easy to keep your belongings organized. The mesh pockets allow you to see the contents at a glance, and the X-shaped belt prevents your belongings from falling out.
Secure TSA combination lock
Equipped with a globally standard TSA lock, it can be safely used at US airports (including Hawaii, Guam, and Saipan). The keyless combination lock protects your valuables without the risk of them being lost.
