Like your feet, if you get cold hands, it can be game over for the rest of the day. You will spend the first hour of your day sitting at your computer begging your fingers to move over the keyboard as they sit there completely rigid.
It is best to opt for a waterproof pair as any others will be a waste of time in poor weather. Waterproof, windproof gloves are often not the most stylish but they are the easiest bit of kit to whip off and into the safety of your handbag as you glide into a meeting.
When choosing a glove, it is advisable to go for a snug fit as this will keep your hands that bit warmer. A bike specific glove will also come with some grip and often padding around the fingers which will give you a little added control of the bike especially when it is wet and also take a bit of the pressure off your arms when you are riding on uneven roads.
