My Dakine flannels are getting worn out so I was also looking for a new one.
Got the Enduro one, which is nice, but a bit slim on the fit.
Also have an Oakley one. Very nicely made, but a bit too cotton for riding.
Then I found an Adidas flannel. Heavy weight & technical material. Buttons instead of poppers aren’t ideal, though it does have a stealth internal chest pocket.
I did like the look of the DHB, expensive though.
Wish Dakine still made good looking gear, it’s all a bit meh these days.
