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.”
