The bag is nice and light. I've used it for dayhiking and as a commuter. Organization is good, and the bright interior makes it super easy to find stuff. Padding on the back is sufficient but can get sweaty, same with the shoulder straps. Two issues: mesh on the side pockets is too weak (I'm a desert hiker, things get scraped), and there's no hang-strap or similar for a hydration bladder. Any pack with a hydration port (which this has) should have at least a loop of 1/4" webbing to suspend a bladder. As a commuter bag, I feel like the laptop compartment doesn't have enough padding for a very heavy (ie corporate-owned) laptop. You will feel the laptop through the back, and it might ding a corner when you set it down. But there is more than enough space for all of your paraphenalia (chargers, writing tools,etc) and a non-insulated lunch.
