The Aquabloc Down Gauntlet glove places 600-fill goose down on the back of your hand (for warmth) and thinner synthetic insulation on your palm (for dexterity). The three-layer waterproof and windproof shell keeps out external moisture, while a wicking inner liner moves perspiration away from your skin.
Flexible lithium polymer batteries—seven grams each—power a heated layer inside the Red Savina to warm your fingers for up to six hours. The on/off switch is hidden inside the wrist gauntlet. Water-resistant goat skin and heavy Cordura nylon keep snow and cold on the outside.
The same things that make a glove warm—heavy insulation, wrist gauntlets and synthetic shell materials—can also make it bulky. Guys who prefer greater dexterity will prefer a glove like the Workhorse, with supple water-resistant leather, a simple elasticized wrist and 200 grams of Thinsulate insulation.
