AquaBloc is Gordini's proprietary waterproof, windproof, breathable technology. Engineered exclusively for hand wear, our seam-sealed AquaBloc inserts allow moisture molecules to escape without letting water molecules in. It is the best of both worlds: let your sweaty hands breath while staying warm and dry. DownTek Water Repellent Down is insulation that has been conditioned with water-repellent-nano-treatment. A proprietary application method instead of a bath treatment is used, thereby eliminating waste run-off.
