Setup, Compatibility & Care
To ensure the longevity of your backpack, store it in a cool, dry place when not in use. While the polyester material is water-repellent, it is not waterproof; use a rain cover if caught in heavy downpours. To clean, wipe the surface with a damp cloth and mild soap. Avoid machine washing or tumble drying, as this can damage the internal padding and specialized compartments. Always check the specific personal item dimensions of your airline before your flight to ensure optimal fit.
