Great value trekking/backpacking rucksack with many features. Start off with a 60 litre capacity and expand up to 80 litres if needed as you go on your travels. Split main compartment with a bladder pouch for hydration system if required. Side expandable pockets with zipped side entries, mesh bottle pockets and a zipped front pocket all add up to a deceptively large sack. The lid also has 2 pockets - external access and internal mesh and a compression bungee on the top, plus it is expandable via the external straps to heighten the bag overall and provide more space inside the main compartment. Comfortable adjustable harness with breathable mesh and padding on all body contact points.
