What Redditors Say
Best praise vs top criticism for Osprey Nebula
Top Criticism
+3 pts“Agreed. Also I think most bags look ugly, including the Nebula. I'm not a bike-riding DoorDasher - why do most bags have to look like that? At least some of the tactical bags look sharp. Different strokes for different folks, I guess.”

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.”
