The Sonju is a spacious 35 Liter Campus backpack from Granite Gear, with multiple compartments, a weather resistant exterior and a full suspension system. The Sonju is divided into four consecutive compartments so you can keep your things organized. The main compartment holds a Gear-Tec laptop sleeve that’s padded and can handle up to 17” laptops and the outer pocket is home to a multi pocket organizer perfect for keeping track of smaller things. On the top of the pack is a stash pocket with a water-resistant Barrier zipper. This pocket is also tricot-lined to keep your sunglasses and smartphones from getting scratched. The entire body of the pack is constructed with a combination of Repelawaeve and Taurpalite fabrics which are tough as well as water resistant. The exterior of the pack also features stash straps, a floating front panel, two zippered side-pockets and dual stretch mesh hydration pockets. If you prefer a hydration bladders, there’s also a port for that.

Thanks to Granite Gear’s trail tested load carrying technology, the Sonju supports loads well and makes carrying heavier items much more manageable. It is comprised of ventilated load absorbing shoulder straps, a padded hip belt with a convenient zippered pocket and a substantial, ventilated back panel. Additionally a sternum strap spans the gap between the shoulder straps and serves to stabilize the load, while built-in load lifter straps can be tightened to pull the load even closer to your center of gravity.

The Sonju is a large pack and is designed to carry large loads comfortably. Its multiple compartments, weather resistant construction and advanced load carriage system make it an excellent all-around pack and a proud member of Granite Gear’s Campus Collection.

  1. Nearly Perfect Review by dodasgirl

    This is a great bag, has all the pockets and spaces that I was looking for. Love the thick, strong, waterproof fabric and comfy straps and buckles. The "nearly" comes in because it is just too tall. I am 5'5" and it hits my head and my butt uncomfortably. I still use it and just deal because it's great in every other way. My hubby is 5'10" and it's a little long on him as well, but not uncomfortable. I wish they had taken 2 inches from the height and made the bag bigger the other way (protruding from my back out).
