This unit handles crowded public transit, long campus walks, and multi-day travel schedules with absolute ease. Measuring 46cm x 30cm x 13cm and weighing a lightweight 0.90 kg empty, its softback framework maintains a structured, comfortable silhouette on your back. The rugged Oxford exterior requires minimal maintenance, allowing you to wipe away surface smudges or rain droplets with a quick damp cloth.

Inside the pack, the smooth polyester lining forms a gentle backdrop for delicate tech accessories, notebooks, and personal items. The thoughtful compartment layout ensures that smaller accessories like charging cables, power banks, pens, and keys remain instantly accessible instead of settling at the bottom of the main chamber. Finished with a comfortable soft top grab handle and smooth custom zips, this unisex backpack brings effortless practical utility to your working routine.
