Not for hard core MTB who wants tactical control
The gloves did a fair job in keeping my fingers warm at 35 to 45 degrees. The problem with these is that they have an inner liner that is attached but causes your fingers to shift about a 1/2 an inch within the glove while the outer part grips the handlebar. Therefore causing a false sense of control. SO if you are a hard mountain biker that likes control, then this is not your option.
