Marigold Industrial Glove
Black rubber, medium length gloves which combine some toughness with sensitivity and flexibility. Obviously, completely waterproof (when new!); quick to dry, too, as they are unlined.
They can be worn over neoprene diving gloves to protect your investment, if underwater digging! Also, of interest to divers, these are the gloves traditionally provided for use with the Kubi Glove System; therefore they are the appropriate replacement.
Take a couple of pairs for long trips away.
Sizes: 6.5 (small) to 10.5 (XXLarge) so there are suitable sizes for children or small handed female cavers, but also yetis.
