Comfortable and compact, the Kahuna 18L Backpack was originally based on our popular Kahu Backpack, but has now become an iconic Macpac pack in its own right. With an expandable laptop sleeve, this versatile backpack is all you need when getting around town or hiking in the hills on the weekend. Made from a tightly woven oxford nylon fabric, the Kahuna offers everyday durability and basic weather resistance during summer squalls. The lightly padded harness features a breathable mesh overlay for warm weather adventures, while the front and internal zip pockets are perfect for stashing small essentials and keeping your wallet safe and out of sight. At 18 litres, the Kahuna isn't too big or too small — it's just right. Designed for an active lifestyle, the Kahuna is equally compatible with modern technology, commuting in the city, or hiking in the hills.
