Perfect gloves
Color: Black (001)/Jet Gray, Size: Medium
These gloves are warm yet, not bulky. The fit is a little on the snug stretchy side but not tight.

Amazing!!!
Color: Black (001)/Jet Gray, Size: Medium
I work outside in brutal temps all year and have yet to find gloves I can actually have dexterity and warmth with. These are everything I’ve wanted and more! I have no complaints and they fit amazing.
