SealSkinz® Chillblocker Gloves, this wrist-high waterproof glove is insulated with a liner made of expedition-weight double velour Polartec® Power Stretch™ fleece. The outside layer is a knit of nylon/lyca® spandex offering a durable, flexible, stretch covering. The palms are covered with a gripping pattern of unique abrasion resistant dots. Chillblocker Gloves are designed to be slightly larger than regular SealSkinz gloves to help promote warmth within the glove during extreme cold weather. If you prefer a 'snug' fit, we suggest selecting one glove size smaller than usual.
