At first I love how the bag suited my daily commute needs, it was the reason for buying it anyway. But quickly got into the habit of taking it for day hikes with my camera and its size is perfect for overnight light hike ins or packing for a few nights out at a friends. The cell phone/sun glass pocket is easily accessible while the bag is on your back even keep a quick access cards I need up there. The bottom pocket is a bit of a mystery to me still. I've found it's a good place to keep things you wont need regularly or that you tend to grab when stopped to get into it.
