The BitterBlaze Aerogel Gloves are the award-winning handwear that uses the waterproof trustworthiness of GORE-TEX®, the resilience of Pittards® Oiltac goat leather, and the revolutionary warmth of PrimaLoft® Aerogel insulation used in NASA space travel. This compression-resistant thermal barrier is patterned over the palm and fingers of each glove, with multiple panels that allow retention of grip and freedom of movement. Each customized Aerogel insert reduces heat loss from freezing cold elements, like ice, rock, tools, and rope, allowing you total focus on the task at hand.
