It is my experience after buying most every type of glove there is and using/testing them in logging as a cutter and with a cable skidder that these gloves are the best value if not the best glove period for logging and firewood related work, and unless some place new has shown up, the below link is the cheapest link for them.
Never tried it on a chainsaw but I have made some decent grip modifications to the handles of commercial mowers to reduce vibration transfer to operator in conditions where gloves are just not practical.
Excellent pt. Tape used for tennis rackets work good too. It's improved greatly over the years.It took 20 posts to get to the point, put something on those grips and you will do a lot more good that gloves. Others have mentioned some padded tape that cyclist use on the hand grips, I find a piece of heater hose slipped over the original metal handle adds both vibration protection for your hands, and a very nice grip.
Also, try to notice how you hold the saw, a lot of time we hold them with a GI Joe death grip when that is not really needed and the fatigue combined with the vibration really takes a toll.
