A black, water-resistant travel backpack built to hold a 15.6" laptop and everyday essentials. The pack uses an expandable body with 3 compartments and can grow from .8" to 11" thick to accommodate light or bulky loads. Crafted from 1800D Oxford fabric with metal zippers for durable performance in busy settings like airports and subways. Comfort features include an EVA airflow back panel that reduces sweat for all-day wear, padded shoulder straps and an adjustable chest strap for added stability. The main compartment opens in a 180° lay-flat design to speed TSA security checks, and a luggage strap makes attaching the bag to a suitcase effortless. External Type-C and USB-A charging ports let you charge a phone without opening the bag, and a hidden pocket provides a secure spot for valuables.
