The Lectra Gloves are waterproof, durable everyday gloves with the added benefit of having battery heat when it gets extra cold. The new design gloves have snow cuffs to seal in the warmth while keeping the cold out. On those extra cold days or to take the chill off, just turn on the heat by inserting in a “D” size alkaline battery which will last 4-6 hours if used continuously, longer if used intermittently. Safe, comfortable, perfect for all cold weather activities.
