FAQS
How does the 3-tier expansion actually work?
How does the 3-tier expansion actually work?
The bag is engineered with a Modular Zip System. You can physically unzip the base layers to expand the bag from a 28L daily tote to a 40L weekend bag, and finally to a 58L high-capacity duffle. This allows you to scale your storage based on the mission.
Can I use this as a "personal item" on flights?
Can I use this as a "personal item" on flights?
Yes. In its most compact (28L) mode with the wheels detached, the bag physically fits within most airline "personal item" dimensions for under-seat storage. When fully expanded, it functions as a standard carry-on or checked bag depending on your airline’s specific limits.
Are the wheels durable enough for rough surfaces?
Are the wheels durable enough for rough surfaces?
The snap-on 360° wheel system is built from high-velocity, wear-resistant polymer. While designed for smooth terminal floors, the reinforced housing physically protects the bearings from grit, and you can detach them in seconds if you need to carry the bag over rough terrain.
Is the material actually waterproof?
Is the material actually waterproof?
The bag is crafted from High-Density 210D Oxford fabric, which is physically water-resistant and tear-proof. It provides systemic protection against rain and spills, though the internal Bio-Isolation compartment is the only zone designed for 100% moisture containment.
