Expands from a 28L day pack to a 32L travel backpack for 15% more packable space. The easy-to-clean TPU divider keeps items organised and prevents odour, moisture and dirt from spreading to the rest of the bag; it also tucks away when not in use. Padded storage protects a 15.6" PC/16" MacBook and 12.9" tablet. Outer shell fabric, lining and mesh are made of 100% recycled polyester from recycled plastic bottles. Internal zipped pocket stores a phone, charger and other small items during travel. Thule Aion Travel Backpack 28L
