I bought a pair of Snow Deer gloves a few weeks ago after a friend showed me his. They retail for about $150, which he paid, but I bought mine on Amazon for $130 on a Black Friday sale.
As more become available I thought forum members might be interested in my impression of these gloves.
First, they are very nicely made and are warmer then my Klims, even without turning on the power. Each glove has an Iridium battery on the inside of the gauntlet base. They batteries charge within an hour using the double pole charger. I'm told by my friend that they last about 4 hours on the medium setting. The controls are on the outside of the gauntlet and can be seen in the pic. They have three settings which are controlled by pushing the button on the bottom. A spare set of batteries is available for about $40 but I'll never need them since I only use the gloves for short rides on a cold day so to me the battery gloves would be very useful for commuters. They heat the entire palm and fingers to the tips so on a 33 degree ride my hands were totally comfortable.
They have sturdy knuckle guards in case of the unexpected "get off" or also for one of those rare occasions when one must deal with some loudmouth. Never me of course.
I had given my Gerbing gloves to a friend because I only used them a couple of times in the last 8 years or so. I only used them for about two hours in the early morning and didn't like fussing with the supporting cable bundle and control.
The run just a bit small so, while normally an XL glove size fits me a bit loosely, with extra room at the finger tips, these are reasonably snug. I couldn't even get my hands into my friend's size large.
About the only thing I find on the minus side with them is what I consider to be an under sized gauntlet. They are very difficult to get over the sleeves on my old First Gear synthetic jacket and a bit less so on my leather jacket. Overall I'd recommend these to a friend. And yes they are waterproof.
There were many to choose from on Amazon, some for quite a bit less money, but I was not familiar with any of them.
