I do all my own work on my car in some stupid condition . a month ago i change the thermostat on my jeep outside when it be 30 degree outside . grant that be not subzero , but these glove surprising keep my hand decently warm and still able to tight screw by hand and do some pretty nimble task . from other review I read I be surprise by how warm they keep my hand and how much tactile feel they do remove . do not get I wrong these be not a winter work glove and these do keep much more tactile feel than other glove , but read other review you would think they be a second skin . I would really recommend the ` fast fit ' style as well because I always have task I need to take they on and off for work on car . all in all these be excellent glove and well worth the ten dollar I pay for they . they seem pretty durable as well . but we shall see !
