Tom Bihn Synapse 25

Review

The Synapse is on the small side with only a 25L capacity but should do well on shorter and warmer trips. The warmer the weather, the smaller the clothes can be. People generally don't pack big clothes during the summer months.

One feature that some people overlook is that the Synapse 25 has a lot of O-rings all over the place which makes customizing for more adventurous travel easy. With extra O-rings, you can easily clip on water bottles or other things you want to keep handy but don't want to be loose inside your pockets. I always throw copies of travel documents inside a plastic bag and attach that to an O-ring.

Internal Frame

The Tom Bihn Synapse 25 has a removable internal frame which will keep the bag much more sturdy. I like the inner frame because it gives you the option of a nice and soft quicky bag for quick trips or a rigid frame for when you need to maximize space.

My biggest question about the internal frame is if it feels comfortable on your back. Remember when you were a kid with heavy backpacks with a billion books? I remember the backpack I had was always loose and floppy, but it was always comfortable. Some of the more rigid packs are uncomfortable.

I've only worn the Tom Bihn for short periods of time, so I'm not quite sure what the verdict is.
