These gloves are awesome once you get them on. They're cozy and warm. The four finger thing makes perfect sense -- it keeps your two smallest fingers warm together without sacrificing any utility. I feel like a crazy crab-clawed guy when I'm wearing them too.
But BE CAREFUL WHEN TAKING THEM OFF. There is a warm inner liner that is not attached to the outer shell. It's very easy to pull the fingers of the inner liner inside out. Once you've done this you can't put the gloves on until you straighten them out, which can be _extremely_ difficult. "How hard can it be to turn a glove the right way round? Trust me -- when there's a shell in the way, it gets tricky. I recommend chopsticks if you do find yourself in this bind. Last winter I left these on the shelf for about 6 weeks even though they would have been the perfect warm glove because I couldn't get them on!
First, I'll start off by saying that I'm living in west central Wisconsin, and I have been biking about 3 miles round-trip to class almost every day this winter. I will also preface this by saying that I may have Raynaud's disease, which causes lack of blood flow in the extremities in cold weather, so basically any gloves that I have worn in <20 degree F weather have not kept my hands warm. That being said these are definitely the best ones I've owned for biking. I also have a pair of leather gloves and a pair of wool gloves/mittens that have 40 gram thinsulate lining. In comparison to those, the Planet Bike gloves are not as warm when you aren't moving, but once I'm riding the wind resistance of the Planet Bike gloves keeps my hands noticeably warmer. Despite this the gloves are not as water resistant as I was hoping for. Its been raining the last few days and the palm of the glove gets pretty wet quickly.
Here is a rough temperature breakdown of the gloves on my 1.5 mile rides
<0 degrees F - My hands go numb and freeze
0-15 degrees - hands still get really cold, just not as fast
15-20 degrees - the gloves keep my hands warm enough for that ride, I can still feel them when I get to class.
20-35 degrees - Gloves are perfect, my palms get a little sweaty but my fingers are warm enough
up to 45 degrees - the gloves are a little too warm but still useable
