Mittens are the best
I really love these gloves. I have had many pairs of gloves, but none keep me warm. I just switched over from gloves to these mitts, and I will be sticking with mitts from now on. I have very small hands (Size 4.5 ring finger). People often joke that I have child-size hands, and I bought the size 6. They are perfect.
The fleece liners are removable and very soft. The gloves aren't really bulky, either. My hands get cold very easily, so on super-cold days I wear a pair of Smartwool liners.
