Sounds like a great day out!
After a certain amount of trial and error, this is my choice of head/face gear:
Musto peaked cap (with ear flaps)
Dirt bike goggles (like ski goggles, but with clear lenses)
Fleece "snood" (tube) to cover mouth and neck
This has the advantage that you can wear as much or as little as the conditions demand.
I haven't tried a Gecko helmet, but I can't find anyone who likes them very much. They seem like a great idea, and the RNLI obviously rate them, but all the ribsters I've spoken to who tried them said they were uncomfortable and noisy. Helmets in general seem to be much less popular than they were a few years ago.
