Keep warm with a great pair of cold weather gloves
Wear warm gloves appropriate to what you'll be doing
A nice set of skiing gloves may keep you toasty, but they're hardly appropriate when wearing a suit or out on a date. On the other hand a slick pair of leather warm gloves doesn't really cut it when out shoveling the snow.
Wearing the right pair at the right time helps a lot when choosing the right pair of warm gloves as you'll see further down.
Owning multiple kinds of gloves is the best way to make sure you're wearing the right type at the right time. Also, don't forget to keep a pair in the car, after all, it is called a glove compartment.
A warm glove is made of the right material
Select a winter glove that is waterproof and windproof. It really makes no sense to think your wearing warm gloves when the cold air, snow and rain just passes right through it. Those knitted gloves really are useless and should never be considered a pair of warm gloves.
Instead make sure you choose a glove that is most certainly waterproof and windproof. Leather is great at both, as long as there is a liner.
Warm gloves have the perfect lining
Often overlooked but possibly one of the most important features of warm gloves is the lining. It is brutally important that the pair of warm gloves you wear has a lining that wicks away moisture. Any natural material is fine, an insulating material is even better for thin gloves like leather dress gloves. For warm gloves while working the insulation part isn't as critical since you'll be moving around and staying warm anyway, the material must wick away moisture otherwise your hands will get cold quickly. Warm gloves have a liner that will wick away moisture, remember this.
Make sure the warm gloves have the proper coverage
Any glove worn while working should most certainly extend beyond the wrist and even have some straps (velcro) to allow you to close them against your coat. Having this feature will prevent cold and moisture from entering the top of the glove.
A dress warm glove can safely extend to only the wrist, since you'll most certainly not be moving around too much.
