I was given these as a birthday present after I moaned about getting wet (and cold!) hands whilst sailing and wearing the usual sailing gloves. I tested them out whilst sailing in torrential rain off the West Coast of Scotland. To begin with, they kept my hands nice and dry (in comparison to my sailing companions who had very wet hands) but after a while, my hands did indeed get as wet and as cold as everyone elses. I have to agree with some of the reviews on here, I think the flaw is in the design of the cuffs which are not waterproof. Taking my gloves on and off throughout the day meant that the cuffs got wet and therefore eventually made the rest of the gloves wet.
The gloves aren't bad if you dont ever need to take them off (i.e a cyle ride) but for activities like skiing, sailing etc. where you are constantly putting your gloves on and off, I wouldnt recommend them.
