Gordini Aquabloc VIII Glove - Men's: Shell: Flex fabric and 3 layer thermal ply waterproof, windproof, breathable fabric Synthetic liner palm, fingers, thumb, and wrap caps Insulation: Megaloft insulation with Hydrowick microdenier lining, and ultra breathable, waterproof, windproof Aquabloc insert Features: Aquabloc - Aquabloc is Gordini's proprietary waterproof breathable windproof technology. Exclusively engineered for handwear, this is an insert technology that allows moisture accumulated from within the glove to escape and provide for breathability and enhanced warmth and comfort. The molecules of the insert are wide enough apart to allow moisture to escape, yet close enough together to guarantee that water will not penetrate the glove. These inserts are seam sealed, so stitching from the gloves will not interfere with your Gordini glove's performance.
