Which gloves?

I've had Reynaud's in my fingers for many years, usually sailing after a break for lunch. My solution (which works every time) is to stand up in the boat and wave my arms rapidly, one at a time, in a windmilling motion; the centrifugal force pushes blood to the fingertips and restores the circulation. It sometimes attracts a rescue boat.

Hands, Rooster glove liners with cheap diy gloves over the top in winter to keep the the hands warm and protect the the inner glove but then just the cheap gloves in the summer as a helm or crewing in the Merlin, in a RS400 always use Gill championship full finger gloves with a spare pair in the buoyancy aid (2 pairs just about last a year handling the spinnaker halyard and sheets)

Showa 306 and rooster poly pro liners.  Showa 306 have a latex coating so keep the worse of the water and wind off, I then use them by themselves in the summer.  

Yes Sam, they do get a bit sticky if left scrunched up in a sailing bag in the heat.  But after a few months?  They are disposable, so I'd be doing well to get more than 12 races out of them as crew in a spinnaker boat, probably ditch a pair every month or after a couple of windy open meetings.  The ones I now use are thinner versions of the Showa dipped builders gloves.  The 451s I mentioned in the earlier were my winter kit and I do admit they are better for warmth than dexterity.

Builders gloves (£12.99 for a pack of 12 on Amazon) with a pair of Rooster hot hands underneath in the really cold stuff.
