"The Synapse's organization was perfect. The main compartment held a light jacket, laptop and a couple of notebooks. If I needed a pen or my small pocket knife then it was right there in the side organizer pocket. I was constantly in and out of the other side pocket, which held my smartphone and sunglasses. The bottom front pocket held a snake charmer with my cables. The top front zippered compartment held my water bottle and a large tote umbrella. My keys were in the smaller front zippered pocket along with my train pass in a Tom Bihn pocket pouch. I'm always paranoid about losing my train pass but the pouch attached to the pack via a key strap tethered to an O-Ring gave me peace of mind that the pass would always be there when I needed it."
