These fingerless mitts will keep a guitar-player’s hands warm while allowing for unmatched flexibility. The ultra-wide thumb gusset allows the fingers and thumb to move together with greater dexterity than conventional thumb designs. This stretchy thumb gusset allows the fretboard hand to easily finger complex chords, even wrapping the thumb onto the fretboard à la Tal Farlow, without restriction or interference. The picking hand thumb and fingers move more freely than with conventional thumbed mitts.
