It's hard to put into
It's hard to put into words how much this is an upgrade from my old camelbak backpack. It's more comfortable, has better storage organization, and overall works better. When walking, the harness position can be a bit odd, but once you're in attack position on a bike or motorcycle it disappears. My only complaint is that when the 3l bladder is full to the max it deforms the bag a bit and doesn't sit right, but that problem goes away shortly into the ride after you've taken a few big sips.
