hand warmers work great, toe warmers not so much...my ratings are on the hand warmers, I wouldn't buy the toe warmers again
These are useful for providing a quick source of heat on those long winter day hikes or during overnight winter camping trips. For day hikes we usually use them after the midway point in our hikes by placing them inside of gloves or mittens. For winter overnights, we place them in our socks, gloves and hats.
