I always thought the wearing what looks like horse neck harness would be bloody awful. Geez I'm good at wrong!
I wore it for two long and hard days and hardly noticed it was there, amazingly easy to live with. It really did blow me away!
The opening and closing system made it easy to put on and take off.
It's light and perfectly contoured. At no stage did it interfere with turning my head or flexing my neck. Adjustment for my chest shape was easy and quick. My hydration back pack could be put on before or after the collar. It'll be part of my adventure riding kit from now on.
In a word impressed.
