"The new Tom Bihn Synapse 25 is the larger 25 liter/1526 cubic inch version of the Synapse (now called Synapse 19). For those familiar with the original pack, the Synapse 25 keeps much of the original design. The multiple pockets, which don’t cannibalize space from the main compartment, are still there. So is the 1000D Cordura Nylon exterior, 400D Dyneema Riptop interior, water resistant YKK Aquaguard zippers and bulletproof (made in the U.S.A.) build quality. In essence, Tom has taken everything good about the original Synapse and incorporated it into a larger package with some tweaks to make it even more user friendly. Let’s take a closer look."
