Full finger cycling gloves are a great item to have when the temperature starts falling. Many of these gloves feature a "Windstopper" material to help block and keep out the cold wind. Another nice feature a cycling specific glove gives over a "normal" winter glove is overall thickness. These are thinner which allows you to grip the handlebars better. This is important especially when the roads are snowy and slippery. Even though the gloves are thinner, they still maintain heat, and keep you hands warm even when it's freezing outside. Most gloves also have some sort of padding or silicone in the palm area to help pad your hands. This will reduce fatigue.
Overall, full finger cycling gloves are very handy to have in your cycling apparel bag of tricks. These can really help you get through some of the colder weather seasons.
