Perfect Gray Man Pack: Tom Bihn Synapse 25
I have to say the quality of the pack is outstanding. Its tough but also lightweight. The Synapse 25 starts at $170 and upgrades can be had. One thing for sure, this pack will last a very long time.
Overall this pack is exactly what one needs for most EDC stuff. It offers survival signaling items as well as organization. It blends into the city and in the wilderness (if you get the subdued colors). After reading this you can see why I call it the perfect gray man pack.
