It has been a while since I went to the Galapagos. I don't really recall what kind of suit I wore. However, I do recall that I used a pair of gloves that were dual thickness. I just did a bit of searching and I found them again online. The brand is Seasoft. They make a 3mm/1.5mm glove that would fit the bill. Thumb and forefinger are 1.5mm, 3mm for the rest. Kevlar fingers and palm, which is handy due the barnacles in the Galapagos. Not inexpensive, by the way.
