Incredibly clever design of the GSI Outdoors Commuter JavaPress removes the intrusive plunger rod from classic French Press designs and replaces it with an inner mug that creates a double wall of insulation to keep your coffee or tea hot, while eliminating blow by grit. This blissfully warm wake up call, this deep breath of rich, bold liquid sunshine, is exactly what you need to endure those morning commutes. Clever alternative design to traditional French Press. Spill resistant, flip top lid seals in heat and sloshing, unscrews easily so you can stir in cream, sugar, etc. Comfortable foam sleeve adds a layer of insulation for both your hands and your coffee. 15 fl. oz capacity inner carafe. Non slip foot. Size: 3.8 x 3.0 x 7.8. Wt. 9.6 oz.
