Hello, first post here.
I'm not new to bags but I did just get my first Tom Bihn Synapse 25 and LOVE it.
I have had almost every high end brand pack out there and this one is "the one" if there is such thing.
Anyways my question about the YKK zippers is, do they smooth out a bit over time, they are kinda hard to pull due to the aquaguard.
I do love the YKK zippers, I won't buy a pack unless it has YKK.
Is there a type of zipper lube that would help?
