Made of the same lightweight, indestructible material as Nalgene bottles. This press brews gourmet coffee or tea out in the wilderness just like the French cafes in the city. A double-walled lid helps retain heat, and an insulated neoprene wrap adds insulation in cold weather. Ideal for the camp or country picnic. Two sizes: 20 fl. oz. (6.1", 10.8 oz.), 30 fl. oz. (7.7", 10.3 oz.).
