The Odyssey Gamma Backpack is that easy, no fuss, do-it-all backpack that's got plenty of space for everything you'll need for a day at the park or just a day out. It's built from a tough material with a reinforced base material, with padding at the back & the straps for comfort. The Gamma has a large main compartment with plenty of space for everyday essentials with a padded laptop sleeve & an external zipped pocket. Two debossed patches on the front of the Gamma allow you to lash extra items.
