I own the Dakine Titan mitt and love it. I just leash the mitt portion to my wrist and when I need my fingers I pop the mitts off do what I have to do and then pop them back one. They are super warm, almost too warm at times. I often pop the mitt off while on the chair for a few minutes. The mitt itself can be worn with out the liner of course. I have never had an issue with getting wet, and I fall down a lot...lol Just my opinion though.
I'm leaning towards the Dakine Titan. I usually wear a size M for gloves, should I go up 1 size to L since the glove comes with a liner?
