I could mention that when helping on the yard I always wore Woofwear fingerless gloves and still do. When grooming I like to be able to touch and feel the surface of the horse, to ckeck it over, and it is easier to tack and untack with no glove cover. Those fingerless mitten gloves were always warm enough for leading and even riding too.
But not massively waterproof when handling hoses I seem to remember. At the RS there is automated watering system but at the big house the "conservation grade" stable has no mod cons.
