Anchorage Gloves. Gloves are warm, and work very well at -4 degrees F. (coldest temp tried yet) with full heat. Also warm without any heat at 25 degrees F. Customer service is also excellent, very responsive. Had to exchange for a larger size, and had a return label from them within 2 hours of my request, notification when they received the returned gloves, and a new larger size received by me withinin one week of my initial request. The sizing chart to determine hand size for the gloves is way, way off - toss it out. My hand palm circumference is just under 8.5 inches (measured both hands multiple times before ordering), which is borderline small/medium according to the chart. Had to return the mediums (8.5 - 9.1 inches), and even the large size (9.1 - 9.6 in.) is tight, can't completely close my hand, and feeling the tightness when holding a hiking pole. Hard to believe that a glove's hand circumference over an inch larger than my hand is still too small. The gloves are also difficult to put on with the batteries installed. The area of the glove located at the elastic wrist area at the top of the battery is too narrrow for the hand to pass through (backhand strap completely loosened). No problem putting on the gloves if the gloves are put on without the batteries installed. Despite the sizing problems, they're so warm I'll keep these, and use them just for the colder days. Hopefully they'll loosen up a little more over time.
