Best praise vs top criticism for Tom Bihn Synapse 25
Top Criticism
+5 pts“They sit too low on my back. Tend to be “droopers” and I like mine up high. I tend to prefer Evergoods and GORUCK for backpacks. I have a Synapse 25 that I need to sell at some point but it just isn’t a fit for me personally. It’s a well made bag though.”

What Redditors Say
Best praise vs top criticism for Boundary Supply Errant Pack
Best Praise
+8 pts“Let me say a few things about the errant considering I carry it daily. The organization is very good, plenty of pockets for everything. It it also very unique looking, rugged and fairly waterproof. The cons are that its not light when it’s empty. The flap is a little finicky but you get used to it. And the shape of the bag makes some things fit weird inside. All that being said, I still really like the bag and would definitely buy it again.”
